Local dive shop rummage sale -- picked up a Aqualung LPO octopus regulator for $5 (no hose). Checked it out using a first stage and it does breathe, although not all that easy. Are they hard to rebuild? I like the idea of less bulk, and having a spare that I could put in service if needed seems like one of those "not to bad" ideas. I did open up the purge button/cover it it looks pretty simple in side, but looks can be deceiving....
I looked on line and found the service manual but it speaks to a number of special tools that are required. Any one have any experience with the LPO and servicing it?
