everyonedoesit is good but they only have german models. There is a Roor US.
i don't know what position you are in but it may be hard to buy a bong sometimes. It could take a while to find something but DO NOT SETTLE.
And don't just go into any smoke shop and ask for the most expensive bong. Man, oh, man, I have seen some scams. Educate yourself on good manufacutrers. I like U.S. tubes too, they are made in US (duh) and come in a variety of thickness. Like they have a nice thick ass 9mm toob. Also 5mm and 7mm, but those are more standard.
Sooooo, there are some forums on the web about glass that can get you started
www.tokecity.com - no competition to RIU in terms of grow knowlage but they do have a lot of people that are into glass. Bongs, headies, etc. Be careful you will see the word SICK posted more than ever before. or SSSSIIIICCCKKKK. that is pretty much all you are allowed to say without getting your post removed.
www.glasspipes.org is also really cool. This site to is mostily about headies, you are probably just looking for a standard glass piece like all of us. They have some cool stuff to drool over. Very nice.
www.thataintart.com - Check this site out for sure though. This shows all my favorite artists in one place. Very cool stuff.
All my bongs are just clear, that is really the way to go, then invest some good money into a heady slide (bowl) and you will have a nice setup. Also look into getting those k clips (spelled different i know) they are awsome.
Some places just don't have a good glass scene, or any for that matter. If you are in CA, CO, NY, or around those state you will be ok, but some places you could make a journey out of picking up a good glass piece.
Like I said in my other post, I like dementia, they wont stear you wrong really, and you can check out the high end stuff that no one can afford.
Good started company is Roor, they even have some good bowls by mike fro. Roors are available is quite a few stores these days so you should have good luck.
Even get a little bowl like this one from Kennaroo
very nice and simple. you could get this for like 65-75 bux no problem.
here is some mike fro pieces like roor makes
and stoble is a really good artist.
Just look around, I am not trying to advertise for any one particular shop, it just depends where you are at really.
