I actually have the old sahara stem (the hand made egyptian one, now sitting on a sub zero vase
) and have been using it more than any other hookah lately, nice big gauge, purges awesome. Though I can't say the same about their new mod stems, I really don't like the screw on parts, stem, hose adapters, plus the autoseal. Just go with an egyptian or syrian. Out of the whole new sahara setup I'd only get an ssc vase if you like them, the dish vases are great and very stable.
