nikko
I have a Nikko Sterling 3-9 by 44. I have had a really good experience. It is crisp, holds zero, and I like mine in that it has a 30mm tube.
I paid $260 new about 5 years ago, and I recently listed mine for 175 on the forum and I had no bites. Mine is in perfect shape, orig box, etc... Perhaps I asked too much, but I am not in a big rush to give it away.
Apparently they have switched over to China and the quality, as I have heard, went down. If the one you are looking at is 10 years old, it should be a Jpn-make.
