I would agree to an extent. There is alot more problems with quality control at the $300 price point for roofs but there definitely are some good units out there. I have owned several I would call respectable by high-end standards.

As for porro vs. roof...there are other issues as well. Close focus distance, speed of focus, etc.... that might stear folks in the direction of roofs. I love the image my Nikon E provides though I prefer the handling and larger eye relief of the LX. The waterproof/splash proof issue is arguably a moot point. Unless you hunt in extremely humid conditions I can't see where it would be a major sticking point either.
