Place where I can find interesting multiple chamber bubblers/glass?

I've been searching all over for some cool quad to six chamber bubblers. My buddy just bought a six chamber from chunkyglasspipes.com and it's sick. I want to find a place where I could get so interesting groovy pieces.

Anyone have a thought?

my only thought when you say six chamber bubbler is what a pain in the ass it'll be to fill and empty the water. search glasspipes.org and email an artist you like.
