Turnstiles aren't cheap at all, so the aspiring DJ should check out the USB Mini Turntable for a cuter and cheaper alternative.
The USB Mini Turntable is probably the world's smallest turntable around. Plug it into your computer and you can start making your own playlist and drop some remixes. Built into this little device are real scratching noises, sound effect buttons, volume controls and even tempo variance. You can even use this with your iPod if you want.
The USB Mini Turntable is puny, and it may not have other features like the cross fader, but it'll give you the satisfaction of playing DJ. Plus it's portable, which means you can scratch and mix right in front of your friends.
