I've only had them do a handful of work recently, mostly some small Onan 2 cylinders. After my 340 sat in their shop for almost 10 years, I'm surprised they didn't want full payment up front!
I think the thing is they are not very office savvy. It's 3 guys trying to do everything. They still hand write the receipts! How much is a computer and Quickbooks?? Oh well, the work is quality.
Another good shop for general work I forgot about is Gunn Automotive. They are very reasonable but don't have torque plates for Mopar. For a cheapie build I would totally use them.
