I'm running a Weaver Classic V Series 1-3 on one of my carbines. It was $150 from SWFA and is a killer piece of glass for the money.

Midway has some reviews on it. I was looking at this one or the DMS-1, but the DMS is a real chunk of metal. It weights over a pound...the Weaver is less than half that. Plus it doesn't take batteries...
After reading the reviews and looking at the under$140 price tag at midway. It worth looking reall hard at.
