I had one for a couple of months back when I was shooting 1-2 times a week. I had no complaints about how well it functioned. I paid $245 for it, and sold it for $265 and 5 boxes of CCI Mini Mags. I had a lot of fun, made a little money and moved on.
I would recommend it because it functioned well, and was easy to strip and clean.
For me, my Buckmark Camper and my 22/45 are more accurate. If they made the MP22 in a 5+ inch version I think I'd like it better.
