Expect to pay and don't expect him to drop everything he's doing to do it. If he has 10 bows that were bought at his shop waiting to be set up, you go to the back of the line. I can understand you might want to take somethings to a proshop, but really, why would you need to take a sight to a proshop to have it installed. A couple screws, spacers and or rubberr pads and it's done. I've found that most things aren't that much more expensive at a proshop and many would be installed for free if you bought them there. Those that take time and expertise you'll probably pay for. Personnally, I couldn't look in the mirror if I bought a NEW bow at Bass Pro or some place like that and took it to a Pro shop. A used one of Ebay, no problem...but don't spend your money somewhere else and expect a proshop owner to treat you like a long lost brother.
