Welcome to the forum ohioshooter. I think the k38 is possibly the best .38spl S&W ever made. I'm not up the speed on the prices of the K38 but $800 seems kind of high.
I checked Gunbroker and not a lot of K38's, the ones listed seem to be around the 550-600 area. No nickle guns at all, so maybe 800 is not out of line for a nickle model. Hammer Down well be by soon I'm sure and he has a better idea on current prices than I do.
I actually bought one this week end. I was at my local sports warehouse type store and a guy at the gun counter was asking if they took trade-ins. They don't so I asked what kind of revolver he had. He replied his granddads old .38 s&w he had inherited and he had not shot it in several years so he was looking for something different. (young guys like auto's) We walk out to his truck and he shows me a K38 with a 8 3/8 barrel in 96% or so. Holster wear on the normal spots. He wants $400, I offer $350, done deal, ATM in the store so I took it home with me. It's dob is 1961, cleaned up to be very nice. Exceptionally smooth action.
