Well let's say I decide to do it. How would I go about getting all this? There are no shops around my area that I know of that would carry turntables or vinyls. I could try ebay for the turntables, but what about the other stuff? Any suggestions?

About speakers, are they a must? Can you use headphones? Is there a cheap way to do speakers? I don't want anything big. Just enough to do some personal DJ work. I really wish I had a Mac, that would rock.
