I am certainly no expert when it comes to choosing a scope for a .22, but I do use a bit of common sense when doing so. The rule of thumb, some would say, would be to spend 1/2 the cost of the rifle on good glass. Well, maybe. Some of the suggestions posted here indicate you should spend 3X the cost of the rifle on a scope...that, IMHO, is totally insane and a complete waste of money. Folks, this is a 22, not a 50 caliber BMG. There are GREAT scopes that can be had for under $150.00. Now, some will scoff at this and flame me, but heck, I don't care...it's your money. Some suggestions, depending on what you are going to use the .22 for are : Burris 3X9X40 Ballistic Plex like about $150.00, or BSA Sweet 22....under $100.00 or Barska 6.5-20X50 Varmint w/target dot....under $100.00 or Mueller ATP with mil-dot reticle about $150.00. All of these scopes can be found on Amazon, along with their respective ratings and customer reviews. I have found Amazon to be honest in their reviews, you get to read the good with the bad. Then you get to make up YOUR mind.
best of luck on your quest.
