If you send your head unit to ISC, it won't be out of service for a 'significant' part of the year. When my regulators need overhauled, I send them to an Apeks shop and wait 1 to 2 weeks.
It all depends what you call significant: if you are diving every weekend then missing a few weekends in a row is a long time; if you're not , it's not. FedEx is very inefficient in Japan and takes a very long time; it might be faster if I lived in Florida like you. My Meg now takes off-the-shelf lithium batteries: thank God a friend was on hand to re-wire it, because I wouldn't have known and there was no manual I had on hand to help. I'm sorted: other people might not be.
