One thing to keep in mind is that the Vapman takes 100% of your attention to operate safely, while the MFLB, Solo, or others take far less. You won't be taking vapman hits while you bicycle along a sunny path. All the same, the Vapman is a low tech workhorse that won't likely ever fail you, and it does have a certain charm. The basic model is a great value, but I would in fact take a MFLB with good batteries before it, and a Solo before that. Vaporizers are complimentary and each one is unique. The Vapman offers a flame powered portable with a butane-free airpath in a lovely, portable handmade package, and for that, it is excellent. I do wish the bowl were 2 - 4 times the size.
As the topic has drifted into comparison country, I'll note that I have little problem carrying the Solo around with me personally. In addition, its lack of learning curve makes it easy to share, while the MFLB, FV and Vapman are potential pains in that respect. You won't be sharing either of those vaporizers with fellow concert goers during a loud show.
