woah, why didn't you say so!
okay, everyone gave great advice, but considering what you're going to be spinning FORGET what everyone has told you.
I'm an avid psychedelic trance/goa fan, and a DJ of it. I started off trying to go with the standard all-American way of buying two Technics and vinyl, until I realized that I was stupid... psychedelic trance, unlike other electronic genras, has it's roots in tapes, DATs, and (now) CDs. It has no relation the the vinyl culture, and very little is available on vinyl. Besides, noone wants to lug 200lbs of vinyl to a beach in India and have all their music melt.

So, on that note.. If you NEED to buy a setup, I would suggest getting a package deal setup of CDJs. You can find some pretty sweet deals on the net, but www.animallshops.com seems to have consistently low prices. The CDJ100's are fine, and will get you off on the right foot very inexpensively. I think you can buy a package with them, a DJM300, headphones, and a flightcase for like $600..?.. and that's all fairly decent quality gear that won't loose all it's worth when you try to sell it in a year (when you either quit or upgrade=).
HOWEVER, if you can just practice on a friend's tables/CDJs, before investing, then, by all means, DO IT. It's the best way.

And don't buy music in lots off ebay. That's shitty music. Just keep buying music the same way, I hope, you've been buying it since the day you could sing. Buy what you love. Play what you love. Noone is successful or has fun doing something that doesn't follow what they love.

Good luck! If you're in the Seattle area, give me a shot... good trance shows comming up...
