AIRE rafts - people either love them or hate them. Personally I think they're awesome, the inner chamber concept is great. I've not had a problem with their zipper system, and as a company they really stand by their product. Check out the D series.
Case in point - tore the floor in an AIRE raft on a low water Middle Fork Salmon float - tear was about 16 inches long - but the inner tube was no tdamaged. All we did was to stitch it up that night in camp to prevent snags or further tears. Didn't need any patching. After the trip was over, we ran the raft back to the factory in Idaho and had them fix it up - didn't cost us a dime.
Also, have you considered Saturn Rafts? You can buy 3 for the price of 1 NRS E series. It don't think it's near the quality of the NRS E rafts - but if you're only going to be using it casually over the next 10 years, I'd personally pocket the extra $3K.
Search around the Buzz, there was a thread on that topic, comparing one brand vs. another, use, etc.
