727 or 904?

When I called for a stock rebuild on a 904 the one shop that wanted me to drop the car off and pick it up said $1900. One shop that said dropped the transmission off on their bench and pick it up off the bench $900.
$104 for rebuild kit. $92 for transgo (mr.shift)shift kit. And an hour or two of spare time here and there and done in a week or two. Just think about how long some of you guys have waited to have your motor bilt. Since like triple-R said we have to have internet here and now we start hearing all this stuff. I'd like to have all the transmission guys chime in and tell us how many times they have heard of some home job do it yourself guy messing up a 904 and then bring it to them to fix it? I still say it would be hard to get it wrong.
