Last spring I purchased a pair of Lowrance HDS with side/down scan from Scheels for a better price than I could find anywhere on the web for the exact same models. Plus they threw in the lake chips, which were another bunch of dollars I didn't have to spend.
Sometimes it really can be better to buy local.
The sportshow is in Bismarck this weekend, I'd start there on Friday and then hit the web on Saturday with purchase being made on Sunday from where I decided to give my business.

I think mine are HDS Gen 3, 7" screens.
While I like them, the side and down scan take some time to figure out how to interpret.
