The only thing I disagree with is that there is a certain amount of confidence to be had with a brick and mortar type business. I agree that FLT seems to have the best transmissions, but even they fail in trucks they shouldn't. After you spend $2600 on their transmission, and $500 shipping it and core charges, you are a ton of money in.

I agree, that I wouldn't let that guy even touch my truck. It doesn't matter if you think he's running a stand up business, the dealership wouldn't charge you $12,000 for a 4l80e swap. Charging that much for such a job is criminal.
