You can still get the M91/30s online for around 90 bucks. A few lucky ODT members got a few last week. Shooter grade but still nice rifles.

But like a lot of folks in this thread have stated, the M44s...
Southern Ohio Guns have them in stock for $94 when you buy 3 or more. They are in stock right now. Better quality then the place you mentioned before. I ordered 4 from SOG and they were in decent shape.
