Honestly i'd check out the weedstars. Some people knock them and call them crap but honestly most of them have never even seen one in real life. They are amazingly priced for what you get and there pretty fucking sturdy.
You can also check out Dodoglasspipes.com but sometimes they suck. My friend ordered from them probably 10 times and ended up getting broken shit twice. They replaced them but what a pain in the ass that was, the whole waiting, getting it, finding its broken, emailing pics, waiting, shipping it back, more waiting, then finally gets it. And the thing is the way they packed it even if the mailman played football with it, it wouldn't have broken. SO basically they had to ship out a broken bong for some reason.
And lastly, If you want REAL quality glass, Google Aqualabtechnologies and order from there. So if money is no object and you wanna make sure you dont get fucked in anyway, go with them. I guarantee you will be satified
**edit. Make sure whatever you go with, Make sure Its Glass on Glass and has a diffused downstem( or called diffuser). Don't settle for anything less cause its pretty much the standard these days.
