Thanks for the quick replies.... Shall i take it that no-one knows a 'normal' instructor

The Evo was my most likely target as i would imagine its pretty easy to get parts for in remote places, the electronics are an issue, but im not planning on getting one immediately, so theres lots of time to watch things develop.
I have several thousand dives with various still/video cameras, so im not going to focus too much on them and kill myself (touch wood). On open circuit i still look at my gauges once a dive-ish :sercet: Just dont tell my students!
