I think the PDF X will be my next radio of choice. It looks like a great buy. It's either that or the JR XS3. I don't think you could go wrong with either.
KB, I don't have either one. I just got the Airtronics MX-3, but haven't had time to test her yet. I have my truck all torn apart right now b/c I'm doing some upgrades.
But if you do get either one, let us know how you like it. The only draw back to the 3PDF-X is that is doesn't have the ABS like the rest of their radios do.
Oh BTW, the 3PDF-X is already out, I checked it out before I decided to go with the MX-3.
