Damn...can I just BUY a better transmission for the money than having mine built?

Thanks, guys.
I have considered rebuilding it myself but due to restraints of time, workspace, other priorities (I am a new home owner with projects coming out of my ears! :( ) ...and of a course a lack of experience, I have decided to write the check this time. I'd like to actually drive the car sometime this decade. :)

Any thoughts on that unit that Summit sells?
