Bake bros . com Simply the best price/quality wise, it they have some decent american brand name glass at awesome prices along with very decent pieces on other no label glass. Next is thickqualityglass, and then if you wanna be a china boy go to dhgate and get yourself something fancy for under $40. Look up cleanclearglass and click water pipes. They make all the grav labs crap. Look on the site, it sort of proves how many companies rip people off, even "legit" companies do. And then look up yingmin5, they ship faster and seem to be much higher quality. I had a sidecar form yingmin that was better than most american glass, and thick as hell. but i traded it for real american glass... *i'm not 100% sure grav labs is just china glass with a label, but i'm strongly inclined to believe so, along with many other brands, i wouldn't be surprised.
