I've had a Vortex crossfire II rimfire 2-7 on my .22 for around 6 years now. I've been very happy with it has been beat up a good bit while never losing zero. The only thing I dislike is the eye relief is a little goofy for me at times, or could be a light issue. It seems looking into the tree tops if I'm not lined up perfect its almost a glare or something. Hard to explain. But for the price I like it, Next step up with be a Leupold VX Freedom series with rimfire reticle. The eye relief on the Leupold agrees with my eyes a lot better.
Those are my two "lower" end picks. (still some money but not going to break the bank for the quality you'll have)
