Which lock-up convertor?

Trans is at the shop now. The trans-guys high suggest me switching back to a lock-up. Heard all good things about these but which is the best for repeated locks and dependability in a 10 second car?

I've got the PTS 9x11 and it's incredible, I wish I would have bought one for the GN when the 51 was on it. Bruce has the greatest customer service too.
