That's also a concern that I've had myself. I've read how they have been around as a company since the 70's though so that eases my concern slightly. They are fairly new to the scope market though. I'm curious as to how this will turn out in 10 years, because as of right now they are offering amazing products at great prices with amazing customer service.

If you are going with a Zeiss, which is a step above both of the scopes you originally mentioned one thing I thought I'd point out is Cameralandny.com has some refurbs on sale. I think the 3-9x40 can be had for something like $350 if they have the reticle you want. I'm not sure if the sale prices are listed on their site or not, but I know they have a thread at 24hourcampfire.com about it.
