Vortex Diamondback 4-12x40, is only 189-200. They have an unconditional full lifetime warranty and they have a very well respected Customer Service..
Now for what I know, I picked up several Nikon BDC scopes and checked them out at my local Bass-pro, while they were very clear, the bdc circles were so fine I found myself having trouble aquiring targets in them. I'm 50 years old so my eyes may not be as well off as the next fella. When I picked up the Vortex, not only was it cheaper it was clearer, crisper and the field of view was better (edge of lense to edge of lense) the Deadhold reticle in them are solid dots which for me was easier to aquire targets, but the kicker was that not only was it cheaper in price, it magnified the target better than any of the rest of the scopes in this class... pick one up and try it!
