As I'm sure most of you know already, the AP Valves have said that they're no longer supporting the electronics side of the Inspiration Classic. After talking with AP on the phone, I was quoted the upgrade from a Classic to a base spec 2020 Vision as being a shade over £2.5k which replaces everything in the loop from the T pieces back. After adding a temp stick and the trimix software its just north of £3k. At least they supported the Classic as long as they did! I best start saving... Although I wonder what the next 'my first rebreather' is going to be.
