i have a friend who may have or be building a t5. how much you looking to pay and how soon you need it. he owns his own performance shop and has a good load of t5's in his tranny booth where he goes thru them all and re-services them.
I was looking for one that was used but still running. The car is an 88 cougar so its heavy, but I plan on running lower gears and putting a mostly stock 5.8L in it. I was probably topping out around 300 dollars but could be persuaded to go more if it was in better shape.
