I love mine. I'm in the process of turning a 1942 (non matching) Izzy into a more "modern" gun (commonly referred to by collectors as "bubba-ing", but those guys can eat my shorts) and a M38 (forget the year).
For the price- you can't go wrong. 880 rounds cost about $150 shipped to your door. There's a growing aftermarket for Mosins, as well (ATI, JMeck, BrassStacker, etc.).
They are a hoot and a half to shoot. Especially the carbine versions like the M53, M38, and the M44. If you can shoot these at dusk or at night, the flame is AWESOME.
Looking to purchase another non-matching to turn into an Obrez, an M53 (Chinese), and looking to get a reasonable priced, matching 91/30 to leave stock. As mentioned before, the historic factor is awesome. Mosins have seen action from Europe to Asia (China, Korea, Vietnam, etc.).
My buddy bought an M44 a couple of years ago for $65.00. He's taken it to a few dealers and they have offered him over $300 for it.

Hard to find M44's for less than $200 asking price now. Talk about a good investment.
If you do get one (I might recommend Eagle Arms in Pennsylvania), definitely clean the cosmo out of it. Sticky bolt occurs when there's dried cosmo in chamber. most normal cosmo removal methods won't get that out. Take a chamber brush, put it on a short cleaning rod extension and chuck that on a drill. Fire about 15 rounds through in rapid succession and dip the brush in Hoppes or Purple Power/Simple Green and run the brush through on the drill. Works great. I've used this method on my 2 Mosins and several other mosins that my friends own.
You definitely can't go wrong with one of these.
