I'm looking to buy my first GonG and I have a good idea what i want, i just don't know where i can find a great bong at around a $200 price. Im looking for: No taller then 20in 4mm or thicker Perc 3+arm Diffused Stem Decent sized slide ashcatcher! Unique color combo If anyone knows where a good place to find one with these specs, please let me know. Also if possible I would like to find a nice more valuable used one- if anyone can help me with that. Thanks!
