My impressions:
Gander: Over priced and spotty on wether you get someone who knows guns or not. It's part of their business but not the focus of their business.
Frontiersman: Marv has always been helpful even when busy. (If you ask my wife, sometimes too helpful... I SWEAR he's a ventriloquist and he has the new gun "buy me" voice down pat). Good selection, reasonable prices, layaway program. Lots of rifles and shotguns.
Gun Stop:
Reloading: It's THE place to go. John may not tell you what you want to hear but he WILL tell you what you need to hear

Guns: Great prices that are consistent. No markup and then sale stuff. Good inventory, Great sign out front

Bill's: Rentals - you can try some guns before you buy a similar gun. Only down side is that the rentals could be cleaned much more frequently. Prices vary but they have good selection. Generally knowledgeable staff. I prefer the Circle Pines store and range. It's closer to me, has a different feel to it and is not as busy when I care to go in and shoot. Doug, Ryan, and Teresa are excellent folks. The rest are probably good too I just haven't had a chance to deal with them.
J&S: Been in twice. won't be back. Prices high, workers more interested in their own conversation than customers. Lo-balled my dad on a gun, citing the wrong gun in their pricing. then the price on what he wanted to trade it on was high.
Ahlman's: worht the drive. Rifle / Shotgun selection is incredible!
