I have a Bushnell 3200 Elite 3-9 x 40 and I really like it. The zoom range is excellent for most real life shooting situations and it's 40mm lens provides very good eye relief and a bright image. On some of the higher magnification scopes eye relief can be a real issue. For around $200-$225 online, it's a great scope & it comes with a lifetime warranty from Bushnell. I currently have it on my Bushmaster AR but I'm thinking about switching it to my .270 Remington. As long as you get quality rings, I don't think two piece bases are any worse than single piece bases.
