Deciding on a DJ controller often comes down to balancing condition, price, and the features you'll actually use. These four DJ equipment listings span from a low-cost Numark Party Mix to a Pioneer DDJ-SR that arrives with a Magma soft case. One is open box, three are used or as-is, and the listed prices range from $50 to $350. The goal is to match the right controller to your setup without paying for features you don't need.
Quick Take
In short, the $50 Numark Party Mix offers 2-channel mixing with pitch control and 8 pads; the $100 Numark Party Mix adds a built-in mixer; the $160 AlphaTheta DDJ-FLX2 is the only open-box option with PC/Mac compatibility; and the $350 Pioneer DDJ-SR includes a case but is sold as-is. Choose based on whether you want the lowest listed price, a built-in mixer, portability, or the extra carrying case.

Feature Decision Matrix
| Product | Channels | Key Details | Condition |
|---|---|---|---|
| AlphaTheta DDJ-FLX2 | 2 | Portable, built-in mixer, PC/Mac compatible | Open box |
| Numark Party Mix (Built-In Mixer) | 2 | Built-in mixer, USB | Used |

The AlphaTheta stands out as the only open-box unit and the only one with PC/Mac compatibility. The two Numark Party Mix controllers both offer USB connectivity, but the higher-priced one adds a built-in mixer while the lower-priced one focuses on pitch control. The Pioneer is the only unit with the Magma soft case included and is also the only one with 6.35mm TRS input/output ports.
Product Notes
AlphaTheta DDJ-FLX2

This open-box controller is described as having been used twice and then stored in its box, so it reads as the closest to new among the used and as-is options here. Its listed features include portability, a built-in mixer, and PC/Mac compatibility, which makes it a practical choice if you travel with your setup or switch between computers. The limitation is the open-box condition: it's not a brand-new unit, and it sits at a higher listed price than the used Numark Party Mix listings.
Numark Party Mix (Built-In Mixer)

The used Numark Party Mix with the built-in mixer is a straightforward two-channel tabletop controller. It connects via USB and includes loop and sampler functions, which are useful for live remixing. The main draw is the combination of a built-in mixer and a moderate listed price below the AlphaTheta. The limitation is that it is a used unit with no condition details beyond 'used,' so you should be prepared for the normal wear of secondhand DJ gear.
Numark Party Mix 2-Channel with Pitch Control

This is the least expensive listing in the group, and the description notes cosmetic scuffs on one side and the bottom. It still offers 2-channel control, 8 pads, pitch control, and USB connectivity, so it's a no-frills way to get into a two-deck setup. The tradeoff is visibly used condition and fewer listed extras than the other Numark Party Mix; there's no built-in mixer mentioned in the listing.
Pioneer DDJ-SR with Magma Soft Case

This is the highest-priced listing, but it comes with a Magma padded carrying case, which is a notable extra. The controller is USB powered, has 6.35mm TRS input/output ports, and supports 24-bit/44.1kHz audio. It is being sold as-is, and the seller notes that touch sensitivity on one jog wheel varies slightly and one output port is untested, so this is best for someone comfortable with an as-is electronics purchase.
Final Recommendation by Use Case
- For portability and near-new condition: The AlphaTheta DDJ-FLX2 is the strongest choice, given its open-box status, PC/Mac compatibility, and portable form factor.
- For a built-in mixer on a used controller: The Numark Party Mix with the built-in mixer gives you the convenience without the highest price tag.
- For the lowest listed price: The Numark Party Mix 2-Channel with pitch control is the entry point, as long as you're okay with cosmetic scuffs and a used condition.
- For a complete package with a case: The Pioneer DDJ-SR with the Magma soft case is the one to consider, provided you're comfortable with the as-is notes about the jog wheel and output port.
