Sometimes it seems that all the hookah vendors here Stateside have pretty much the same thing.... or very close to the others wares. Long ago I made it a point to go looking off the beaten path for vendors that sell different hookahs than what we are used to seeing everyday. Hers a short list of a few I found.
Mind you that most of these are overseas companies and the shipping on some of the items are rather high... but if you just had to have what others dont... well. heres a few options.
