I dunno whether "good" really applies to this, but I've gotta say I've been loving the cost, portability and reliability of the Numark DJ2Go Touch ($AU120):

I've got a cute little portable setup using it, a Raspberry Pi 5 with a 1TB m.2 SSD, 15" portable USB-C monitor and a Keychron low-profile keyboard and bluetooth mouse. Works amazingly well.

I'm betting that just about any controller would be worth a shot.

Depending on how much space you have, I'm using a Numark MixTrack Platinum FX, with the mapping from the forum.

Everything works! Even the display in the middle of the jogwheels, that comes with the '4 deck' version, which shows BPM, time left, rotation indicator, shift amount/mode.

At this point almost all buttons & knobs on it are in regular use, although some of the deeper menu combos accessible via buttons aren't fully intuitive but don't seem to matter.

Check the https://manual.mixxx.org/2.5/de/hardware/manuals for a list of built-in mappings shipped with Mixxx. There are also additional user mappings on the discourse forum: https://mixxx.discourse.group/c/controller-mappings/10

Personally, I use the Roland DJ-505: https://manual.mixxx.org/2.5/de/hardware/controllers/roland_...
