Well, I'm on drug testing with about a month left, I figured I was going to need 350 to drop on a big bong at least because in person where I'm from, they we're pretty pricey or at least a few years ago they we're. But I've seen quiet a few nice ones, I'm looking to get something with a Perks I can add a diffuser if there's not already one on the down stem and, maybe if I have enough left over get an ash catcher w/ perks in it aswell. So I was wondering if there's anything specific or recommended company or specs that I should be looking for like at least 5mm thickness, I want something over a foot. I got a bunch bookmarked already but I don't wanna load the page up and I'll be narrowing down the search myself shortly within this month, then I will Post what I finally get here after I'm off the testing in two months. So if anyone could help thanks
