god they are expensive!!!!! from what Ive read the one that seems to come out on top of a lot of polls is the German made Volcano something that resembles a UFO on which you attach a large balloon and toke...it is supposed to be the very best on the market today Price Approx.£230pounds sterling... Myself I use the silver palm which i purchased about 5 years ago and have used it on a regular basis ever since but a vapourizer is on the cards,,,,
