If you're going with vinyl control, I suggest avoiding Finalscratch 2. Users have left in droves to Serato Scratch Live. Just compare their online forums. The SSL forums are full of people who USED to be on the FS2 forums, but not the other way around. I haven't even heard of a single person leaving SSL for FS2, but I personally know several who have done the opposite. I have both, and I can tell you SSL is a better product. Less features perhaps, but it's reliable and priced more fairly. It's also much easier to set up and learn.
Finalscratch hasn't had a software update in aeons, while SSL gets regular FREE updates with responsive support online. SSL is just much more stable and user-friendly. Several of the features FS2 advertises are only available if you also buy Traktor, as that's the program that actually has the features, while both programs use the same engine.
Even the DJ in the Finalscratch 2 online demo video has left for SSL. FS2 could have been really great.
Just ask a Finalscratch owner if they've had any luck selling their used unit for even a third of what they paid for it, while SSL retains a lot of its value right now because users don't WANT to part with it.
Again, chat with some DJs. See what they think of either kit.
