There are lots of different kinds out there. Egyptian, Syrian, Modern, etc etc and come in a large range of sizes. From 12" to 42", from one hose to multiple. Doesn't really matter what kind you have or get. I personally enjoy the larger ones because I feel inhaling off them is nicer and I use mine lots, so why not make it a bit flashy. There are also different kinds of bowl and hoses. I've never found any real difference in the performance of those items. Now onto what you're going to need besides the hookah.
