I've got one. Nothing fancy, blued w/ synthetic stock. 50cal. Shoots good, cleans up as easy as they come. Uses shotgun primers (hot hot hot, and waterproof). I love it!
Make sure you get quality scope mounts and have them lapped. This is a big plus in accuracy for m/l's.
In my opinion, for the price, and ease of upkeep, there's not a better m/l.
