No matter if you go for the preferred glass bong or the cheaper plastic bong, if you go to the right shop you will end up with something cool and crazy. Bong stores such as HerbTools.co.uk have some amazing products, it can actually be hard to pick just one! I myself have been known to spend a full week of pay on a bong, I had no regrets because it had 4 percolators (an additional to a glass bong that sits inside the pipe and further smooths the smoke by splitting it up).
I strongly recommend you use HerbTools for your purchase due to both there amazing customer support and awesome range of bongs and smoking products. Good luck with your search and remember, stay positive. Happy smoking!
