well, as I've posted elsewhere I'm using a "smoke relief" right now which is one of the generic off the shelf types from a random smoke shop. it's decent, better than the other two I've tried in the past. I ordered two riva 510s and some various toys to go with em. Probably going to pick up a few other random bits and pieces in the next couple of days depending on how I like the riva and it's battery life.
I tried dripping with this cheapo because I didn't care about ruining it and it didn't work really. Made a little vapor but not much, gonna fiddle with dripping with the 510s this week if they show up then try one of the random build your own tank mods.
thanks again everyone for the info.
