Agreed...pentax/Burris is your best option in that price range.
The only thing I don't like about my Burris FFII is the eyepiece rotates when you change power..only a problem if you use Butler Creek lensecovers.
Do not buy a VX-1...your getting lame glass, and friction adjustments.
Leupold should be ashamed of those.
Nikon Team Primos for $199 is the best deal going.
Re blue ring...were you inside and under flourescent lights? Shouldn't be there.....
