A DJ controller choice starts with a practical question: do you need a working two-deck setup for mixing now, a portable PC/Mac-compatible option, or a controller intended for repair? These four black tabletop controllers cover those distinctly different situations. The listed range runs from $50 to $174.99, but condition and layout matter at least as much as the number beside the controller.
Quick take
The two Numark Party Mix choices are both used, two-channel controllers, but they emphasize different details: one is described as tested and working with pitch control, while the other is identified with a built-in mixer. The AlphaTheta DDJ-FLX2 is the open-box, portable two-deck choice with PC/Mac compatibility. The Numark NV II is the only four-deck, four-channel model here, yet it is marked for parts or not working and specifically needs volume and crossfader repair. That makes it a specialized project choice rather than a general-purpose starting point.
Listed price comparison
| Controller | Listed price | Price position |
|---|---|---|
| Numark Party Mix - Pitch USB | USD 50.00 | |
| Numark Party Mix - Built-In Mixer | USD 100.00 | |
| AlphaTheta DDJ-FLX2 | USD 160.00 | |
| Numark NV II | USD 174.99 |
The price order does not mirror readiness for every use. The NV II sits at the top of the range while carrying an explicit repair requirement, whereas the first Party Mix is described as working despite cosmetic wear.
Decision matrix
- Want pads and pitch control at the lower end of the range: choose the Numark Party Mix Double Deck DJ Controller 2-Channel 8 Pads Pitch USB.
- Want a used Party Mix centered on a built-in mixer: choose the Numark Party Mix Double Deck DJ Controller, Built-In Mixer, Loop/Sampler, USB.
- Want a portable two-deck controller for PC or Mac: choose the AlphaTheta DDJ-FLX2 Black 2-Deck DJ Controller Built-In Mixer Loop/Sampler.
- Want a four-deck, four-channel repair project: choose the Numark NV II only with its stated volume and crossfader work in mind.
Product notes
Numark Party Mix Double Deck DJ Controller 2-Channel 8 Pads Pitch USB

This used Numark Party Mix is the clearest fit for someone who wants a compact two-channel layout with eight pads and pitch control. The description says the controller was tested and working, giving it a more immediately usable role than the repair-oriented NV II. Loop/sampler capability adds another control option for mixing workflows. Its limitation is physical condition: cosmetic scuffs are noted on one side and on the bottom. Choose this Party Mix when operating condition, pads, and pitch control matter more than a cleaner exterior.
Numark Party Mix Double Deck DJ Controller, Built-In Mixer, Loop/Sampler, USB

The second Numark Party Mix suits a shopper looking specifically for a two-channel tabletop controller with a built-in mixer, USB connectivity, loop/sampler functions, and eight pads. It stays within the Party Mix format while presenting a different emphasis from the pitch-control model. The used condition is the key limitation, so it is not the open-box alternative in this group. This is the sensible Party Mix choice when the built-in mixer is the main feature shaping your setup and a used controller fits the plan.
AlphaTheta DDJ-FLX2 Black 2-Deck DJ Controller Built-In Mixer Loop/Sampler

The AlphaTheta DDJ-FLX2 is the most distinct two-deck option for computer-based use because it is identified as PC/Mac compatible and portable. It also includes a built-in mixer, loop/sampler functions, and eight pads in a tabletop form. Open-box condition separates it from the two used Party Mix controllers and the repair-marked NV II. The trade-off is scope: this is a two-deck, two-channel controller rather than the NV II's four-deck, four-channel layout. Pick the DDJ-FLX2 when portability and PC/Mac compatibility are central to the decision.
Numark NV II 4-Deck Serato DJ Controller Dual Displays Controller Only

The Numark NV II is the choice with the broadest deck and channel configuration: its title identifies four decks, and it is listed with four channels, dual displays, a built-in mixer, pitch control, filter, and loop/sampler functions. Those controls make its layout relevant to a repair-oriented project with a larger control surface in mind. The limiting detail is decisive: it is marked for parts or not working, and the volume and crossfader need repair. "Controller Only" is also part of the title. Reserve the NV II for a project where those stated repairs are expected.
Final recommendation by use case
For an operating two-channel controller, the first Numark Party Mix is the most direct match because it is described as tested and working. For a straightforward Party Mix setup built around the mixer section, choose the second Party Mix. Select the AlphaTheta DDJ-FLX2 when portable PC/Mac use is the priority. The Numark NV II belongs in a separate lane: choose it for its four-deck configuration only when a controller needing volume and crossfader repair suits the project.
