Re: NEED A NEW HOOKAH
FYI - I would NOT suggest putting Dry Ice into anything even remotely airtight with water. I was watching Mythbusters last week and they were making Dry Ice 2 lt water bombs to create waves. It caused a real nice mess.
I would be very worried that if the Dry Ice vapors/gases couldn't escape fast enough from your base jar, it may cause an explosion - sending razor sharp glass, water and dry ice everywhere. And this would be IF the sevrer temp changes didn't CRACK the glass of the base outright!
As to the Hookahs you were looking at, any of them seem nice. IMO - I would skip the ice bucket @ the top unless you like the Look of the bucket on the stem. I wouldn't dare put the ice up there... only in the base itself.
