Personally I prefer Syrian narghiles but some very good Egyptian stuff is available. I'd suggest looking over Syrian products before making a buy.
I don't have any experience with Hookah-Shisha products but i've heard a lot of comments that range from highly positive to super negative. I would suggest that you not buy anything under 26", stay with single hose products and remember that you will not get a narghile with owning for less then 50.
It has been my experience that the best Egyptians are made by El Ashrey and Khalil Mamoun although I have heard a lot very positive comments about Magdy Zidan. In terms of vendors i'd suggest www.hookah-life.com
for Khalil Mamoun and Magdy Zidan. I would suggest getting a small funnel bowl and a high quality washable hose as Egyptian hoses are not that good.
