Not all scopes are appropriate for .22LR. Most centerfire scopes are factory-set to be parallax-free at 150 yards. At distances other than that, one experiences parallax. It is always best to have an adjustable objective, but those are most costly. For me, on a .22LR, I prefer a 4X with adjustable objective and target turrets. I have only seen 1 in my entire life, and I can no longer recall the name of it.
Conversely, .22LR scopes are generally parallax-free at 50 to 60 yards. So, to assume that you can grab an off-the-shelf centerfire scope for your .22 LR is not prudent. That is, unless you intend to hunt at centerfire distances (100 to 225 yards) which is precisely what I do with .22LR.
In closing, cost is the last consideration that I will address. In my experience, there is not a very high correlation between scope cost and scope performance. Determine your intended use, intended distance for that engagement and then buy what works best. Shepard scopes are considered the best 500 yard scopes on the .22LR market, but at $600.00, they had better be! I would not ask for advice at the sales counter. You need to research this one outside of the store.
