I would say glass or acrylic would be good, but I would definately not get anything that is plastic. I got a pretty decently good size one for only $30 and it worked out great. You can also get some pretty large sized ones for around $70 or so. The ones i have seen at that price were about 2 feet tall, super thick glass, and looked incredible. You can get bongs for pretty much any price though, just depends on the size, thickness of glass, looks, etc...Good luck on finding one that you like. They are totally worth it.
