Reply to Scratch Crossfader Or Mixer?

Bought a Numark M3 a couple of months back, come to find out its not a very good scratch mixer...

I was believeing of doing 1 or 2 things, either sell the M3 and get a good scratch mixer (0-$350)

or, Keep my M3 and swap out the crossfader to a a better scratch one

so my question here was, What are good models of 2 Channel scratch mixers or a good scratch crossfader?
