I have always found the bigger the shop,the worse the service!
We have a guy here that runs a small shop out of his basement,and earlier this year my buddy had a cam go out on his martin and had to send it in for warranty repair,and this guy lends my buddy a mathews reezen already set up, just in case his bow didn't get back before season opened.
I have always had good service from small shops,they do it because they love it, not to get rich!
