From what I understand, you are not willing to shell out a lot of dough for a very quality setup. Thats ok, so the next best thing is a beginner setup, or something that comes all together.
Never buy anything with a belt drive. BBBBAADDDD!!!
The absolute best beginner set for the price was always the Numark phat pak, in my own expiereinces. They dont make them anymore, so if you can find a used one, go for it!!! Im selling one now, but just locally. I put it up on ebay once and it didnt sell, so im gonna wait a few weeks, but it will probably be gone by then.
Stanton in the past has made some fairly decent starter systems. Id look into those. Gemini and Stanton tables are apparently the same, but Stantons mixers are a little better, so I would not go with any gemini stuff.
American Audio has had some stuff. Not to bad, but defidently not the best. See what you find there. Im real cautious when I say that to.
Thats all I can think of right now. Some websites have pre-setup beginner sets. Try and find some of those. Most notably are
http://www.audiolines.com

Those ring a bell. Might wanna check those out.
Now, im giving you advice most people on this board would never mention, unless they are putting it down. That is to buy a beginner set. Im not even suggesting it, but it is an option, and it seems what you are most interested in.
DJing is a very expensive hobby, so if you dont want to put down the money, it would be smart to not try. I spent a little over $1200 on all my equipment, and just in the past 2 weeks ahve bought $40 worth of vinyl. Im so broke right now, especially since I have no income, as im only 15.
Thats all I can think of for ya man. Ill get back to you sometime if you need anything.
