RE: scope decision
I own 2 ProStaffs, & wouldn't hesitate to get another.
Still, I'd line-up all 3 scopes & see which one your eyes like best. Just make sure they're focused correctly for your eyes before you start. If possible, put a target outside the store at a good distance, then see how clear that shows up through each of the scopes. It would be even better to try it at dusk.
Another thought: it seems like they're having fire sales at several places on the next level of glass (Burris FFII, & even Nikon Monarch) at very near the $200 price point. If you can get into glass that good for only a couple o' shekels more, I think it would be a wise investment.
Good Luck,
