Keeping up with traditional DJing has been tough on me as vinyl gets pretty expensive especially if you want all the new stuff. I've messed with Serrato which let's me use my digital music and regular turntables to mix them but this new concept created by a student named Scott Hobbs in Dundee Univ. would be cooler to have. While he is working on to make the product marketable you can go to his design site and drool.
