scope suggestions for sr-22

Have decided I have to buy one of these. One problem however is I'm 59, near sighted, and even with glasses have a problem focusing well on front and rear sight with traditional sights. ( hey I still do OK, but not like I want)

Anyway, don't know much about scopes. Want something simple, not too expensive, and most of all easy to use. I see some use a "red dot" scope?

Any suggestions would be appreciated. Thanks!

Center point At your loco wall-mart

Primary Arms M3($99) or M4($89), both are quality optics for their price point and have 4 different reticles to choose from including a 2MOA dot and a crosshair, all very crisp, the best customer service I have experienced to date, and the owner stands behind his product and his word. Everyone over at arf.com loves the guy and his products.
