Thanks folks. Yeah, even though I haven't played it myself I have a gut feeling the action on the MOXF8 would be average at best.
As I've mentioned in the dedicated thread I started, the keybed on the Casio Privia PX5S, that I just purchased last week for £660, is superb. Very nice piano etc., too.
You need to try it for yourself... in the end noboddy can know what kind of feel you like and whats acceptable for your standards..
