Re: hookah on the go (smoking in the car)

The Leila will do everything you are asking for but is more expensive than what you are looking to spend.
Other then the witch and hobo-hookah I don't know of anything. Also be warned that even if it is being used for a hookah base, driving with an open alcohol bottle in the car is still illegal and an easy way for a cop to screw you if he thinks he can't get you on a drug charge.
