My brother and my father both have Polk's radios. I believe that one of them had a minor quality control issue with the power switch, which was immediately taken care of by Polk's (not that hard to do, since their sales rep. lives about 15 miles away from my town). Anyway, both seem happy with their purchase, and it does have a heckuva lot more memory than my Eclipse 7. Incidentally, if you didn't already know, the Tracker II was designed by a former Hitec engineer.
