I picked one up a few months ago for a family member use at an Appleseed. It isn't bad, but is certainly not top of the line. No aftermarket mods for it or anything like that. If you want a basic semi-auto .22 for less than $150 you can't really go wrong with it. You get what you pay for.
I've got one thats beat to hell and real rusty, and shoots every time and is pretty accurate. I bought it awhile ago for $60. I slapped a sling on it, and now it makes a great woods/camping gun.
Got one from Walmart for $130ish... for what it is, I love it. I bought it for an extra Appleseed rig and it fills that void nicely. Out of the box I think its every bit (if not more) accurate than my 10/22.
It is no frills tho and there isn't ANY aftermarket parts for it. What you see is pretty much what you are stuck with, but for a cheap plinker... its great.
