I've made more mistakes with scopes because I didn't have one to look through before I bought it. I have lucked into some good ones, and NONE of them were made in China. Mistake 1, I get a reticle I don't like, but the glass and scope are great. The reticle may cover too much of what I routinely shoot, maybe it's too busy, or too fine for low light shooting, Glass - it's worth the price to try to get the best you can get. With good glass in a solid scope you make hits at ranges that are tough for poorer quality scopes. And, It's great when you can actually see what you are shooting in detail. For example, a dull/hazy 20X is not as easy for me to work with as a sharp/crisp 10X. Zero stop, for me it's worth some extra expense to have a zero stop.
I have 2 Sightrons with the MOA reticle I like: S-Tac 4x20x50, S-Tac 3-16x42. I also have a Slll 6x24x50 zero stop that is awesome, but it has a MIL dot reticle I don't really like. I also have a Nighforce 3x15x50 MOA that is good, but it's on a rifle I hardly ever shoot.
This site has some good info, but I don't think it's being updated. It has a lot of info and specifically tells you where it's made and gives some reviews on each one.

I guess in a long winded way I am trying to say do your research, talk with your buddies (and take a look through their scopes) and don't get in a rush. Some really good deals pop up if you are patient and look hard enough.
