Anyone heard of/have experience with pro-star.com?

I finally settled on a laptop (http://www.reddit.com/r/SuggestALaptop/comments/mv7gt/gaming_laptoprefurbished/) as a Asus G74SX-XR1 with a few extra additions/upgrades.

However, I was originally looking to get it from xoticpc.com from another redditor's suggestion (as well as some fantastic reviews of them), but have stumbled upon pro-star.com. I can get the same laptop for about $100 cheaper. My hesitation is I only found one place that reviewed pro-star.com, which was resellerratings.com (the difference being 23 reviews for pro-star and 486 reviews for xoticpc).

Any information on them would be fantastic. Thanks again reddit saviors!
