38's are really tough to find these days. I'm looking for one myself but would prefer a 38 stock. 44's are not much better, even the Type 53's are getting hard to find and prices on those on GB are approaching $200 in rough shape.
I've seen some of the 91/30 prices and scoffed at them, then later checked the auction sites and they seem to be getting it. While I doubt they will ever match the mausers, at the going rates, I've trippled my initial investment on most of them. When the dirt cheap ammo dries up, I can see the price dropping again. A lot of guys buy them for the "bang" factor at the range and when the ammo gets too expensive, there are a lot of nicer rifles out there.
