Hey all! BigDaddyVape, thanks for the response. I was all set to get that same bubbler, but the site requires your billing address to be the same as your shipping—fixable by sending in a photo I.D. to them, which I don't really want to deal with (I go to college in a different state than my card is registered to).
I ended up getting this guy:
http://www.grasscity.com/us_en/black-leaf-sunny-afternoon-inline-perc-scientific-glass-bubbler.html
which I think belongs in this thread! It's $88 but I was able to find a 20% off coupon with a quick google search—shipping was obscene, of course (E.U. glass), but it came out to be the same as the normal price w/ free shipping after the coupon. Neatly fits under the $100 mark.
Black Leaf isn't the best, but is at the upper end of china glass, from what I've heard. Seems like good glass for less than the price of most others—it's even inline like the headford bubbler, which I've heard is great for water diffused vaping.
Also got the 14mm whip adaptor off of ALT, and the tubing BigDaddyVape linked. From the earlier discussion, it seems like they'll fit together. It was this or get the MFLB water pipe adaptor, but one thing I don't like about the MFLB adaptor is that to use it the box must be at a certain angle, and stationary—and that angle won't be horizontal with the bubbler I ordered. I like the idea of the whip because I can keep the box completely horizontal, and even shake it around while heating (which I sometimes do to keep temps relatively low and even while building good vapor).
Haha sorry for the essay—really excited!! I've spent way too much money on vapor equipment recently, but if it lets me toke with no to minimal irritation so that I an be at 100% for my sports, that's all that matters.
