it appears that scuba.com can service IDI regs (out of business in 2003?) - i had it serviced in 2002 but well, oops;) (internet purchase)

so, hopefully for less than the cost of a new reg;) (was good for 400 dives;))

got a new wetsuit coming too...nine weeks from friday - bonaire

Check out XS Scuba - they picked up the IDI line and rebranded it (along with some Parkway stuff, as well as some original stuff). You can use their 'dealer locator' link, or you can contact Mike directly.
