The biggest Issues I have with a PBC are The Price... Way to expensive for what it is! Once you light it it has to burn until it's ash unlike a UDS that you can snuff out and save your fuel for the next time. I'am real Frugal guy and I can use 400.00 and build one that won't waste fuel for less that a 1/3 of the asking price. and spend the rest on beer and meat.
