I did a writeup a while back -

One update is that since that writeup I have added an LRTS and a PST II to my group. The DMR II hangs in there with the others for sure, it is the most expensive but I'd also say it is the most robust. They are excellent scopes and have improved upon the original DMR with better multicoating which provides a better image. If you're in need of a short, tough, reliable scope then I don't think there is any better in this price range. I would also recommend the illuminated version which has the best daylight bright illumination I've seen in a long range scope.
