Get a nice glass on glass bong. If you have a lot of money to spend try and get yourself a roor. If you're in the states you can go buy one from a head shop or online at everybodydoesit. Here are two of mine, the first is a US 18" roor then 2nd is a 8" german:
If you want to spend less money but get sometime of equal quaility pick up an Ehle. They are made in germany and are super nice. Really beefy joints. You get get them online at showmeglass.com which is a very good site, the guy that runs it is very cool. Here are some Ehles:
If you want sometime with a little more modern try a LUX. They have really nice tree perc so you get extra filtration, plus you don't want an old dome perc. Here is my LUX mini which is 14" and have one 4 arm tree perc (plus my ash catcher):
I will leave you with this one last picture (which isn't my stuff) to inspire you get get something cool. One toro the rest are ROOR.
Hope that helps you some.
