Personally, I've found that Radio Shack dealers are much less annoying than the stores outright owned by Radio Shack. They're usually named something different (like "VanMannen's Electronics" back in my home town), but since they're independently owned they get less pressure to follow you around and pester you. They also tend to have a bit more diverse selection and have better customer service.
yeah at the cabin there are 2 of them...one in Aitkin that is an office supply shop too and the good one in Brainerd (Sound Communications). I try to hit that one for some good stuff.
