well to somewhat answer the questions, having it rebuilt to stock means you'll probably end up having the same problems that plague the paper mache DSM trannies usually have, in that you'll burn up synchros really fast. I mean spending the money once to have it built up would mean more peace of mind in the long run but a lighter wallet in the meantime. If the price difference bettwen stock and built is feasible then get it built. Hearing that 2nd and third gear grind is a horrible sound for your sanity and your wallet too, but making the tranny last longer will prove to be a great purchase.
