You're probably better off buying one directly from them if you really want one.

If you don't mind waiting, then the wait for a used one could be worth it though, depending on price. Good luck finding one; hopefully it won't be too long a wait.
This. If you do luck out and eventually find one used, it will probably run you about $4500 for a used TS2. Then you need to pay for the tune on top of that, another like $800 or so.

But I LOVE the TS2 kit, oh baby is it hard to stay out of the throttle!
