I thougt it would be more expensive, only 20% added to the selling price in the USA sounds good.
I got the 3 channel DM3001X. I can clearly hear a little sound degradation, but its not so bad. Also because I have very good speakers. It features 3 band equalizers for each channel and kill switches. No effects. I guess it would cost around USD 275 at your door. The difference with the DM3002X is that it doesn't have separate channel VU meters. You would still be within your budget.
You should consider a 3 channel mixer if you also want to connect your laptop. Or you shouldn't mind using the input selector switches.
What soundcard does your lap top have? Only digital or also RCA outputs?
Also look at the Stanton C.303. It features a bigger jog than the CDJ-200, but it has no MP3 playback or effects as the CDJ-200. But it's a little cheaper.
You should also think about a headphone remember? And good ones are expensive, at least USD 100. Are you then still within your budget. I assume you already have decent speakers.
