John Willett: I never got the impression the distributor was trying to punish me - I didn't say anything about how it was acquired.
Anyway, the adaptor can't be used with the FR2-LE, as you suggest, so I'll need the original. Still waiting for a price on that one (it wasn't in stock).
However, I've heard from a couple of people who say they hardly, if at all, use the power supply, so I'll try and see how I use the unit before making any decisions.
A generic 12VDC adaptor will most probably also work.
