Ben's in Renton, Fed Way Discount Guns, and Mary's have great prices. I do like West Coast Armory for their selection and the prices are quite reasonable. Matt is super helpful.
Wade's and Discount Gun Sales are on the real high side. Although they do have a great selection, if you're just window shopping. DJ's in Bothell is ok, but not a great selection. The small shop behind Target in Wooodinville is very small and overpriced.
