Reply to What to buy next?

Here is my current setup: TP2, Akai APC20 for 2 Deck + 2 Looping control, DDM4K in Midi mode for Mixer+Effects. I also have a Stanton Str8-80 TT hooked up so i can throw on some vinyl if I'm in the mood. I really wanna get a DVS system with either CDJs or TT's. I have some money coming in I don't know how much but at least a few hundred. My wife is getting me the Audio 6 for a present so that just leaves the CD'J's or the Vinyl(I'll tell her about the Traktor upgrade price later :P)

What would you all suggest. Buy a used pair of say denon DN-S****, buy a single Pioneer CDJ-350/800 or wait and buy something a little beefier. Another option would be to pick up another TT which are fairly cheap (500$ or less for pair of used Techs)

I love my DDM4K but I would prefer to use it in mixer mode rather than Midi mode and I believe with the CDJs/TTs I would love the feel a lot better.

Any suggestions?
