@Pop Rockerz, you didn't mention what you are getting the tt's for. Mixing, scratching listening, sampling?
Can't say much about Gemini's though, never used them. But as you probably know based on your post, you get what you pay for. So it might well be that you find yourself looking for new tables in a year or two and may have trouble getting good money back from the first ones.. Have you considered buying piece by piece and looking at used turntables?
@deanlofts you would also need a dj-mixer as you'll be doing the cutting with the crossfader.. Unless you want to stick to babies and skribbles that is.. So you wouldn't be using the usb but rca connectors from turntable to the mixer and from there with rca connectors to the software's (Serato, Traktor what have you) interface. And with that you'd use the software and the time coded records. You'd be even able to make mixes from mp3 with one turntable as you can switch the "deck" in Serato and Traktor.
For scratching I wouldn't recommend going cheap. You'll need a direct drive tt with good torque and a battle mixer with a cross fader that's intended for scratching. I'd look for Technics sl-1200, Vestax PDX2000 or Numark TTX (and if on budget I'd try looking for a used table). Mixers Rane TTM 56, Ecler HAK's, Vestax PMC's, maybe look for older second hand HAK (310, 320, 360) or PMC models (05-pro ii/pro iii)
I got Technics SL1210mk2's and Ecler HAK 360 mixer. I don't use dj software.
