I've been pretty impressed with the new Redfield scopes. They're clear, easy to use, attractive on a TC carbine, and the price is right. Of course time will tell how well they hold up. I picked up a 3x9x50 with the ballistic reticle for $175.00 plus tax because I had the local gun shop order it for me. Since they know me well, they only upcharged me 10% since it was what they called a "guaranteed sale".
I'll also agree with Woods and Martineta, used scopes are a good way to pick up a nice piece of glass. Especially on the big name brands that have a lifetime warrantee. There's a NIkon Monarch 2-10x50 with side focus at the local shop for $400.00 that I'd love to have. It's got a rub on one of the turret caps, but that's ok, I can order another cap, would save about $400 over the price of a new one.
If budget is not a big concern, then I really LOVE my Leupold 3x9x40 "European 30" that I have on my 375 Winchester. I also really like my Burris 2.5x10x50 Fullfield that I have on my 7mmTCU barrel, although it's a little bit harder to adjust. Both scopes are in the $400 - $500 range.
With glass, you get what you pay for, with a point of diminishing returns in the $500 range (my opinion).
