Re: Which Hookah should i buy?
KM are usually good for heavier smokers (if you like lots of smoke and not a very long lasting bowl)... KM's last long, and hold their value as they are of the top egyptian manufacturers, along with Majdi Zeidan (which is a bit more expensive)
Your other option is to go with a Syrian (preferably a Nour hookah). They are heavy duty made (solid brass) and outlast most other hookah. They don't quite smoke as heavy as KMs ('cause they're made for the bowl to last longer).
But like the others mentioned, Khalil Ma'moon or Syrian "Nour" would be the best. Some of them look really good too, if you like traditional looking oriental hookahs...
My 2 cents
