The thing about the footbox is you have a footbox for your feet but nothing for your head. I tried a BB once and didn't think it was that great. My suggestion is to try one if you can before you spend the money on it. Ask if there is someone close that has one and if they would like to do a weekend trip with you or find one of the group hangs.
"If animals could speak the dog would be a blundering outspoken fellow, but the cat would have the rare grace of never saying a word too much."
