well if you played trance and house, i think you will be still looking at the same type of equipment....
but the most important thing here is, the money. so what are you willing to spend.
i started with these, used at a pawn shop for 150.00 a pair.
http://www.guitarcenter.com/Numark-B...75-i1155398.gc and then bought a stanton mixer, that was like 70$
after three months time, the mixers crossover was shot, and i got a numark mixer.... and again, three or four months after, the crossover was shorting out......
i broke down and bought this

i will tell you its worth the money!!!! ive had this mixer for 6 months or so now and i keep it clean, and lube the faders. no problems yet.....
so, if you can find those numark 1625 turntables, and the djx 700 mixer, get it. unless you have the funds for this
http://www.guitarcenter.com/Technics...13-i1156092.gc now i have two of these and a djx 700 mixer.
now when i get 1500 bucks ill probay get a higher quality mixer. either allen and heath, or a vestex, or pioneer.....
after you have gotten a little setup, and the skills and you know you are wanting to invest money, go get the pro stuff.....
but basically find what you can afford without buying belt drive. and i dont recomend direct drive other than for finding out if this is what you want to do. you need technics.... or vestex,, and numark now makes nice turnatables. but still only techs man.... its the best and havent changed for 20 some years.... they are the best in my opinion.
