I'm training for a 6 day, 5 night backpacking trip on the Pacific Crest Trail, can't sleep without a cpap, and RespShop's rental program for their ResMed Mini means the difference between doing this trip I've dreamed of and not. I don't mind the rental deposit, as it will end up back in my account when I return the machine. Sort of like short-term savings :-) PCT, here I come!
