Other options are when a year or 18 months is up is to get the Head Serviced by ISC by upgrading the head to the latest version.
Thats what I reckon - upgrade and service the head with ISC at the appropriate juncture. With me it'll be after maybe 9 months of diving, but it'll be after over 50 hours personally on the unit and I feel the head needs to be serviced and updated. Will service the regs locally at the same time since I won't be able to dive the darned thing anyway.
