10x- Thats a very good deal on the Nex-gen. I did my first 3 OW dives with my Nex-Gen on Saturday and I was very happy with it. Check out Bare's website they have a wide range of sizes. That will give you an indication of what size you need. Then go to the store and see what size he has in stock. The LDS owner should be able to help you with the fit, and trimming the seals if you buy the suit.
See if the owner will throw in free/discounted training with the suit.
