Roughly $400 and another 5 pounds of gear.
Edit: I wonder if, like high end bear canisters, these will be rentable?
Possibly...but I wouldn't chance it. Recognize that hotshots and jumpers, who's entire REASON for living is to be in the thick of things, statically NEVER use these things. A rental is just not worth it. You can get out of the way, especially if you're not being paid to be a barrier. Also: would you rent climbing gear? Fire shelters wear over time and you don't know how they've been abused. Hint: even sealed in box they've been abused.
Given 24 hours - you can get out of the way. I agree with digging in and what have you, but if you have 24 hours - or even 12 - a special olympics candidate is going to win the time trials. Stop thinking and start moving.
If I were going to carry another few pounds, I'd carry water. Even in a forest fire.
