does it exist? Im looking to upgrade my bong, just a little 12 tube with a three arm tree perc and ice notches, i dont want to buy a whole new tube as there kinda expensive in this time of my life but i would like to get a precooler for it. I want this because it will give my bong more volume for bigger hits and a much smoother one at that. I have been lookng at the showerhead percs for awhile and i feel that i want one pretty bad. I can get a tube with one for around 300, i have not found any cheaper then this but if someone could point me to a precooler with a shower head perc or even a tube that is 200-250 i would be very greatful.
