Re: Khalil Mamoun?
Pirate Hookahs and Pimp Your Hookah are good vendors so i'd recommend them. I would also suggest Hookah Life which everyone that has used them speaks highly of. Lastly, I would recommend Sphinxhoohah.com which carry a huge and very excellent ice chamber KM unlike those carried by anyone else. The one I got came with an old fashioned all leather and wood hose that is totally unlike the new style KM hoses.
In the end I still think Syrian products are better but you can't go wrong with a KM.
