GONG. Glass on Glass all day. You can get a cheap glass bong for $50 or so. It wont be very tall but you can get glass on glass. I have a $180 GONG with ice catchers and a diffuser. It is a champion.
I've always loved glass bongs and bought a pretty nice one last year (I'll putt a link up in just a minute) but then someone broke it... Thats $80 down the drain with no compensation. I never thought I'd be interested in an acrylic bong, but I'm strongly considering getting one since it's going to be making trips out of the house every week.
