Sticker shock on replacing power center

Thanks for all your help Enblethen. You responded to my other post about my damaged Atwood. I ordered a Boondocker from Randy at bestconverter.com per your suggestion. Randy said it is the same size and would just drop in. Remember all the burned wires in the Atwood? Anyway, I really appreciate all your help with this. I just cannot believe the quote I got from this electrician because he said it would take a couple of hours. Four hundred and fifty dollars an hour seems excessive. I called Steve's RV center in Lacombe, LA but I have to drive it over there before they will quote it. I was hoping someone who has had this done could give me an idea of the cost just for the installation.
