Decided.
 

Found a retailer online offering the E20 at a damn good price.
I don't think I could have got a better camera for £804inc postage.
It should arrive within one week.
Now to go looking for CF cards to replace the 1G microdrive that was in the
other one when it was stolen.
I may sell it when the new Sony F828 arrives and we can actually see some
images. The specs make it sound pretty good.
Thanks to everyone for their opinions.
