If you reeeaaaaly want a 4-12X then the Redfield revolution would be OK and about my only reccomendation..... but if you listen to experience you will be a happier hunter.
Honestly $250 isn't going to get you much of a quality scope in a 4-12. You aren't going to be any better off because you are barely going to be above Tasco level of quality.
Trust me when I say put the money into better quality glass and not magnification and size.
