as a friend of mine is fond of saying: "I'm going the other way"
I love my smoking gun and use it frequently.
not hard to keep clean (you just SHOULD clean out the screen after each use, so it never gets 'gunked up'; as any dedicated hashish user from the 60's would already know <g>)
works great, and it's flexibility means I can shoot smoke into the air space in a blender or food processor for integrating smoke into salsas and dips and soups and cocktails and so on... things you cant really do as well in a smoking 'chamber'...and withOUT any heat added
