I got a new WC (Cobra) T5 from D&D for something like $699 but they're starting to get to be hard-to-find. Hanlon had them for about $1000 back in September. Remember if you go the Tremec route though that you'll also need a bellhousing, clutch fork, and different shifter. If you go with the TKO, you'll have to have a different clutch as well since it uses the Chebbby spline pattern. You may also need a new crossmember with the Tremec, but I'm not completely sure on that one.
When I looked at going Tremec, it was going to cost me about $1700 to $1800 to make the swap, but that was a few years ago.
