Somewhere there is a line between function and art.
Since I'm not wiping my ass with $100 bills, I just buy half way decent glass from
www.grasscity.com (nice selection of brands) - real affordable glass is at
www.gogopipes.com - but most is not lab grade glass, so just a heads up. Great for gifts and stuff that you won't want to kill people if they break it on you.
I have also bought from Aqualabs and they are top notch, but a little too high end for my ass! They make their glass using unobtainium! Its hard to find!
