I guess I'll be the odd man out on this topic. I have one a Nikko Sterling Nighteater 3X10 42mm with the side adjust focus that I bought from the NRA online store in 2005?. It was recommended by them as a good buy in scopes. I only paid $150 for it. I have had it mounted on a Mossberg 144LS for a few years now. It is the best scope I have on my .22s. It is clearer than my other low priced Tascos and Bushnells. About the same as my Tasco Euroclass 3X10 I bought long ago at clearance price. Mine holds its clarity at all ranges I've shot at from 10m to 200m. The adjustable paralax has worked for the close range .22lr work and been spot on for focus. I've compared it to others in the same price range and it is better than the Bushnell, Tasco, Barska. I'm sure there are better scopes but the only comparable one I have not shot much with is the Mueller. I'd love to try it side by side with the Nikon brand but most of those are more $$$$.
