T-lo: I would suggest buying middle-low quality Geminis (
www.geminidj.com) to start. Just make sure that you do NOT get belt-drive decks as they're pretty useless and will just frustrate you. If you have the money, I'd obviously suggest getting tech 12s, but there isn't much reason unless you're going to spin 12 hours a day, every day.
So yeah, as long as the decks are direct-drive, then they should be good to start... check out eBay.. I ordered mine through there and got some mint condition Gemini Xl 12 (their top model two years ago) for about 300.. they came with a terrible mixer, but I've since bought a new one... speaking of mixers.. my suggestion is to get a mixer with a 'cue fader'. This acts exactly as the crossfader does, but for the cue (headphones). The mixer I started with didn't have any cue levels, only a switch to select a channel and it made mixing much harder then with a cue fader. It'll cost a little more, but I think it's totally worth it.
Anywho, hopefully that helps.. let me know if you have anymore questions.
