Digital Turntables
There seems to be a lot development within digital turntables that retain an analog feeling. Final Scratch claims to be "New School Technology with an Old School Feel and Appeal". Basically, you have the opportunity to scratch and cut on real viny, along with with having your entire audio archieve available at the touch of a button. It's been used by DJ Craze, among others. I'd like to try it someday, it's sure to be more exciting than software-only solutions like Mixmeister.

Nerd-site, Slashdot has a great discussion thread, from where I'd like to quote this post: "The Pioneer CDJ-1000 [pioneerprodj.com] has beaten this home-brew to the punch. It has pitch-adjust and a substantial jog-wheel that is actually adequate for scratching. DJ Nu-Mark and Cut Chemist have been using CDJ-1000s in their live shows for some time, now."

A dude from Stanford also presents his digital turntable (scroll down) based on a Stanton player. You can check out a video presentation of this product (Quicktime format)
