There are a few shops around where I live and most of them do the same thing in trying to sell you the "best thing in paintball". My and my little bro are not into the Ions and newer items. So we hit up a shop called Ground Floor and the owner has owned fields around the U.S. but ended up selling them. Now he has a nice shop and if the techs can't fix it he can. He even has an ongoing museum in the back with all kinds of guns from the past. He can fix just about anything with a few rare exceptions.
What doesn't kill you, only makes you stronger!
