I live in the US and me and all my friends pronounce SNES as SNess. (And NES as Ness) for what it is worth. It seems to be somewhat common as my friends who grew up on the other side of the country say it this way too.
Look into an office supply / overstock / reseller store around you. When businesses close up shop, they usually sell their desks, chairs, etc. to some kind of overstock store. You can usually go there and get very nice chairs for less then 1/4 of the normal cost
