Hopefully this response won't come off to you as me being a smart ass, but I can tell you from my personal experience, Vexilar's technical support/repair facility is top notch. I broke the gain switch on my fl-22 shortly after I bought it. Sent the entire unit back to them via fed ex with a note included asking them to call me once they got the unit and had a chance to look at it. The tech called me first thing the morning they received it, he replaced the switch, repaired it under the warranty even though it wasn't a warranty kind of thing and because I included a prepaid fed ex label with the package, he put it back in the packaging and had it on its way back to me the same day.
Top notch service in my eyes.
