This isn't directed towards you as it would be easy to assume with all the drama on this board, but I do think other people's opinions should play a small yet valid part in the decision to use a shop. Too easy is it to get deceived just by the kindness and looks of a shop and then turn out to be complete thiefs. I have read too many threads on other boards about this shop that was so nice and then they end up picking their cars up on flatbeds just to get out of the shit they are in with engine builders, etc.
But, because I think all of those shops are a good choice then you can go off personal feelings and appearance of each one you visit.
