don't know of another place that sells that particular rig, but here's a link to a vendor that has a decent selection of brass syrians.http://www.*************.com/shop/index.php?cPath=30_39
these rigs have been reviewded in our review section if you have questions.
also, the narghille your looking at from SH is most likely a syrian and syrian narghille are almost exclusively brass.It's prolly been plated. I'm not aware of any stainless steel syrians on the market, athouogh I could be mistaken.good luck!
