I liked Ben's stove (the one I just bought - for $39.99 + $5.20 shipping) better than another somewhat similar one I found (for approx $150):
http://www.kuenzi.com/home_e.htmI like Ben's design better. It seems sturdier and better engineered. His is not ultralight for backpacking, but I was not after ultralight. It is made of 18ga stainless steel.
Ben is planning to go full production on his shortly. He will be building a website at
http://foldingfirebox.com (the website is not online yet). Sales will be from that website once he's up and running. I lucked out and contacted him at just the right moment I guess, because he had a few prototypes available and was willing to sell me one. He had the prototypes on eBay, but his listing there has expired. Ben said he did not expect a big (if any) price change once these were full production.
