By the way, if anyone can point me in the direction of a company in the south/south east that can try-dive/sell this unit I would be grateful
I really would suggest try-diving one before spending your money.
I've known several people on the south Coast who've had Dolphins but nobody who did more than a year on one. For most diving you're better on on a nitrox 15L with a significant cost saving. We put up with the testing, cleaning and agro of a rebreather to do bigger/more dives than that. They aren't suited to our one deep dive/one shallow dive days and square profiles.
