I've bought a couple guns from High Mountain Hunting Supply in Wenatchee. Yea, it's a 3 hour drive from Seattle, but the owner Kelsey is a great guy to do business with. He will also ship firearms if you're a Washington resident. I did all the paperwork via mail, and he was going to ship to me, but I was going to Wenatchee anyway. He also does a couple WAC shows in Puyallup a year. He just opened a brick and mortar store in Wenatchee a couple weeks ago too. His hours are limited though.
I've bought lots of guns from lots of guys, but this guy is the Les Schwab of gun dealers in my opinion. Unless I can't find what I want elsewhere, I'll go to him.
He lists the 1895 Marlin Guide Rifle on his site http//www.luvtohunt.com at $499 for the blued, and $599 for stainless.
