This is a good write-up about*under $200 Scopes
It was a good write up a few years ago when the Redfield scopes first hit the market. However, since then Redfield's have shot up in price, Bushnell dropped the Elite 3200 line (just Elites now) and they start around $250 for a 3-9 power scopes. Not to mention Nikon has updated the optics on the Prostaff line of scopes.
I'd imagine the test might turn out a little different if ran again with the updated versions of the scopes tested.
