Ordered therm off ebay so will wait for them to arrive and are ok before I give a link.
I bought a s/h FZ18 from LCE at Exeter on Saturday for £120, I am amazed at how much better the EVF is than the one on my FZ28.
Exactly the reason I never upgraded -- I think the behavior at iso 400 is better in the new version, though.
