$75 seems reasonable. Around here I can't even get an appointment to talk to one they are so busy. SM has a good reputation for doing good work quickly. I sold my lathe because it was too much of a bother. I'm with DC, could I do it? Probably. As well as someone that does it everyday, maybe. Is it worth 75-100 bucks to let someone else deal with it while I'm out shooting, absolutely. Life is too hectic with four kids twelve pets and two businesses to use my free time for anything other than things I want to do.

Just thought I'd add another perspective.
