3x-9x ? Nah, what are you really going to be using the 3x setting for? Moving targets?
Srsly... 4x-16 is the lowest I'd be thinking about and 6x-24x seems about right to me or a .22 boltgun. And really, 8x-32x isn't that far out.
Ok, so you're thinking "I said $150!!"... well, the nice thing about a .22lr is the low recoil, so a scope that might be less robustly constructed (IE cheap) will last forever, or until it falls off your motorcycle while you're driving down a logging road
So, go to "futong.com/catalog/item/2129585/1590454.htm" (add the w3 to it yourself) and have a look...
It's a 6x-24x with a "multi-dot" reticle (it's not really "mil-dot" except at a specific power) and an adjustable objective lens (both really nice things to have on a rimfire scope) for about $100, delivered.
As for the quality, I own a bunch of Futong (Fitco) scopes, I've had to send 2 back over the years, one wouldn't focus, right out of the box, and one had the reticle illuminator fail, both were replaced (the warranty is only one year!).
I have an 8x-32x that was mounted on my M14 for about a thousand rounds, then went to my 6.5-'06 for a few hundred and then to my .30-'06 for a couple hundred, and it still works fine. It'll be back on my 6.5 when I get it back together.
Fitco are great rimfire scopes, I suspect that the internal mech. is softer metal, so if you are one of those shooters that do a lot of cranking on the windage and elevation knobs, I'll bet the adjustments will get pretty mushy, pretty quickly, and I wouldn't trust one on hunting gun I was taking on a hunt that would be ruined if the scope failed, but; you get what you pay for.
