I use the Airtronics Blazers, and won the local track championship for super nitro with one. I'm a real tight wad and have a hard time spending that kind of dough on a radio. The biggest issue I have is how much you need to spend on a receiver for each car you own. For the price of one high zoot receiver I can buy two complete Blazer setups, and no I don't have glitch problems and most of the time, everyone else is on 75mh FM and I don't have any frequency problems.
