Looking for a beginner mixer

Using an m-audio xponent as my mixer and although it's great as a controller it can't scratch for ish. So I'm looking for a diff mixer for set up that will scratch well, last atleast a year, work with traktor scratch pro(2) and not cost me more than $200

So far I found (used)
1. pmc 05 pro 3 dx for $125
2. pmc 05 pro 3 vca for $180 (not sure the difference between the two)
3. Denon dn-x120 for $135
4. denon dn-x300 for $150

I use two tt200's

Any help is appreciated

get one of the vestax for around 100

there are always good deals on them on craigslist

Thanks, is there a difference between the dx and the vca? I've been reading and can't find a difference except that the dx is discontinued.

no idea
