ive seen the pst's and they are SICK. you will never find a better optic for the money, or with such a great warranty. i have a regular viper and am getting a pst when they come out. i haven't seen the razor but ive read a lot of reviews from reputable people who say it will compete with anything else on the market. that being said, having looked through nightforces and us optics, i really don't get the price jump (from, say, a $700 pst to a $2000 razor, or other comparable optic). the glass is a little better, and maybe they have a feature or two, but thats a HUGE price jump for what i believe to be a small improvement. its only my opinion, but id try checking out a pst first unless you KNOW you want the razor.

i have dealt with vortex numerous times and their customer service is top notch. i recommend them to absolutely everyone, couldn't be happier. even the viper (which is a middle of the road optic price wise) has seemed to me just as good as any leupold i have ever used or looked through.
