Reply to Get semi pro gear on a limited budget ?

So I've gotten back in to trade after almost 10 years.

I first bought myself a Numark Mixtrack pro just to play around with at home, since then I've traded up to the Numark N4. It's not a bad controller in it's price range, with some mapping tweeks it's a rather compentent companion to Traktor 2.
All though I miss the feeling of the pro gear I became used to back in the day, (well back in the day Numark was pro gear ). I went from SL1200 through Denon DN-2000 and ended up with the then brand new concept from Pioneer the CDJ and DJM 500.

So to the question;

I'm on a very slim budget so CDJ2000 or even 900 or 850 isn't an option, what I'm considering is to get a pair of second hand 800Mk2 or 1000Mk3 to start withm, using them with timecode cds together with my N4 as it do support timecode on it's 2 analogue channels. then when I can afford it get my hands on a better mixer unit, and maybe the NI X1.

So what do you believe is this an reasonable alternative, or would it just be a waist of money?
Pros and Cons, I'd love to here what you guys have to say.
