I'll be purchasing a DBV shortly, as I guess an upgrade from my MFLB. I'm also wanting to get a decent bong to use with it, purely because I want smoother hits as the hot vapors tend to irritate/dry my throat which results in a couple days off vaping/smoking I've never owned a decent piece of glass, so I'm a bit stumped as to where to start and was hoping for some recommendations that would go well with Da Buddha (I'll use it for smoking occasionally too). Price range I'm looking at around $150, could probably go up to $200. If I'm not mistaken there is a water adapter for the DBV but apparently not needed if you get a bong with a joint size of 14mm as the whip fits nicely without it, which would be preferable as buying the adapter would be around $30 alone (with international postage).
If you want to use the bong more for vaping I would recommend a simple tube. In my experience this cools down the vapor more than enough and any percs or added parts will just add drag. I'm not sure where you live but an adapter can be found here for $13 Water Pipe Adapter | Vape World This is the same one I use on my EQ and it works great.
Thanks for the link to the adapter, I'm in Australia so anything is like +$20-$30 postage which is a pain. I'm leaning towards getting the HVY Mini Beaker for $100 plus postage. Was thinking about getting another separate piece of glass for the occasional smoke a bit later on and just use this one for vaping.
Or you could get a travel beaker from ssfgglass for cheaper. Not as large, but cheaper and offers the same solution.
