The Prostaff is a step down from the others in that group and I wasn't overly impressed by the Redfield and I'm not fond of Burris customer service. The Nikon equivalent to the Burris and Weaver on your list is their sweet little Buckmaster. In your price range I would look at a Weaver V10 2-10x38
but if you can afford $240 I'd invest in a Weaver Grand Slam 3-10x40
which is a nice step up from everything on your list.
This ratings list may be of some help.
