I am on my third optic for my 10/22 as I was sort of feeling my way through different options to get exactly what I wanted. I ended up with a red dot in the end because I wanted something very lightweight to accompany my Hogue stock and Tactical Solutions 16.5" barrel. That being said, I tried two other scopes before hand. The first was a Bushnell Banner 1.5-4.5 (found on Amazon.com
here). It was a decent scope for the money, but I didn't love the build quality and it didn't reach out as far as I would have liked.
I bumped up to a Nikon 3-9 (found on Amazon.com
here). I found the Nikon to be of better quality with much tighter fit and finish. The glass was excellent and on-par with scopes much higher up in the price standings. The adjustments were finger-adjustable (no finicky screwdrivers or coins to mess with like on the Bushnell) and they had great, positive clicks. The 3-9 was great for me from distances of 25-100 yards. Like I said, in the end I went with a red dot to save weight and space because I ended up with a shorter rifle. But for a target rifle, I find the Nikon Rimfire series to be both economical and a great value for the dollar. Give them a try, I don't think you'll be disappointed.
