Good point. I think you can send them your T5 and they can do the work on it for less IIRC. With unlimited funds, I like the G-Force T5, especially for it's light weight in light of it's brute strength. It's all about money right? The reasonable gear ratios on a T5 make it a good choice. The T56 is good too, but I have been reading about some gear (1st in some applications and 6th in others) about being unusable, relatively speaking. I could be wrong, but memory isn't totally shot. I decided that if $2000 came up and bit me in the butt, I'd go the G-Force route.
