Reply to Setup advice: Djm 2000 with Cdj 2000 or 1210's with DVS?

Right I'm really struggling to make my decision.
I already own the Djm 2000 but now want to purchase either Cdj 2000's or some Technics.
I learnt to Dj on 1210's then went on to own a pair of Cdj's which I absolutely loved. Never had timecoded vinyls though, so how would technics with traktor/serato face up to the Cdj's? At the moment the way I'm seeing it is I'd have all the capabilities of cdj's for less than half the price. What are the negatives,if any?
Has anybody got this kind of setup with the djm 2000. Any feedback on how you find it works would be great. Also would you go serato or traktor? The only things I'd really use it for is loops and the waveform because the mixer has more than enough effects for me.
Btw I mainly play deep house and techno so would'nt be doing any scratching really.
Thanks guys
