I bought a bong similar to this one last Friday http://gorillaglass.com/images/trip%20acrylic%201.jpg (mine's blue) and have had a blast with it ever since. Mine came with extra end seals and rubber mouth lips so we can take it apart and create any kind of pipe/chamber combination. It's fun since you can either take one huge rip off the whole thing or even break it down to one chamber and have four people smoking off of it.
tight bong. i found it on the site under acrylics and ceramic bubblers. http://gorillaglass.com/acrylics.htm
All the deals on gorillaglass are good. It's the "buy 10 items and total more than $100" wholesale angle that gets you.
