http://sandburrgunranch.comIt's a longish drive for you, but if you've never been and you're in the market for N-frame .44 magnums, Denny Reichard is your huckleberry. DocRocket put me onto him.
I have two, both of them purchased from Denny, with his action jobs. You won't get a good 29-2 for $500 there, but if he's got one, you will get it for a fair price.
His daughter, Ashley, knows her stuff, too. It's worth a drive up just to make their acquaintance.
