If you can afford to spend $539 on a Volcano, go for it. It has ease of use, reliability, precision, and a rock solid company behind it. But don't let anyone give you the idea you'll be getting any more efficiency with bag use than with the herbalAire for $250. I've been using mine for well over a year. If anything it's more efficient than the 'cano, easier to clean, cheaper and easier to make multiple bags, and unlike the 'cano, it does direct draw as well. Yeah, it fills bags slower than the 'cano, but I counter that by making smaller bags and just putting a new bag on for the same bowl load. You do have a separate air pump so there's more 'clutter' to the setup. And the warranty is 2 yrs. vs. 3 for the 'cano Classic (Digit is 2 yrs).Just another way to go if cost is an issue. And of course if you don't like the idea of sucking your vapor from a crinkly bag, you don't want either of these vapes.
