Had a chance to play around with one of those babies today... i must say, they're really
nice.
The pitch slider is very precise, gives great control over the 0.02% steps, as opposed to the cdj-200, which is quite jumpy in this regard. It's not as perfect as on the 1000, but not very far from it.
The jog wheel is amazing quality, fully comparable to those of the 800 and 1000s, with the exception of it being quite a bit smaller of course, and not truly "touch sensitive": you have to depress it a little to get the desired effect, but there is hardly any resistance, so the feel of the jog (esp. for the vinyl emulation, for scratching etc) is almost the same as with its bigger brothers. In fact, you'll have a hard time trying to rotate the wheel by touching the top
without depressing it. And of course, the handling of the jog wheel cannot be compared to that of the 100 or 200 at all. There's a completely different feel to it, much more sensitive and precise, much nicer to work with IMO. But this difference is present in the 800s and 1000s too.
One thing it's lacking from its bigger brothers is the ability to adjust the spindown/spinup speed in vinyl emulation mode - at least I couldn't find that knob anywhere. Not that this is a really important feature, but it's a neat gimmick. On the other hand, it has some additional features, most importantly the USB port, and besides that some (IMO useless) effects. The quick search dial is also pretty neat to have. Other than that, it has the same features as the 800 and also the same quality, just at much smaller size, which is pretty amazing.
So, definitely recommended. Much much higher quality and more features than the cdj-200. Advantages over the 800 is the 0.02 precision and the USB port (and possibly the effects, if you need those), disadvantage mostly the smaller size (which can be an advantage too, depending on your needs), and maybe maybe lack of spinup/down speed knob. Comparison to cdj-1000 is ridiculous of course, both feature-wise and price-wise
