I can swallow the $50 for one of those concentrate bowls - they look pretty clever. What about the bubbler though? Can't believe how expensive they are. I am just a normal dude who happens to be a med grower - I am not a dealer so I don't have that kind of cash and this is not a status symbol or art piece, I need a functional bubbler and thats it. Is there a utilitarian one somewhere? Are the "diffuser" things that much better than a plain old stem? Is 14mm a good way to go? I miss the old days of simple Grafx etc waterpipes, no fancy logos etched in it or glass mushrooms or skulls inside, just a glass tube with a stem! Sorry, its just really frustrating to wade through all this "heady" stuff, I feel like my mom trying to program the VCR.
