Re: Your getting sick of this but help me choose a gift.
I'd say when buying a hookah, go by the rule "if you don't pay enough, you've paid too much."
Basically meaning that you'll end up paying for some hookah you won't be satisfied with, and will probably end up searching for another one.
My first hookah was some shotty 12" something or other...hated it. Spent the extra money and got a nice egyptian...love it.
It may cost a little more upfront for a higher quality hookah, but you will thank yourself in the longer run. (Or in this case, she'll thank you.)
