Should I buy the LX7?

Excellent - thanks for a friendly and informative response 

Indeed the electronic viewfinder is rather pricey at just under the cost of the camera itself.  Sunshine is rarely a problem here (which is why I'm also told not to get quite so excited by the easy access to an ND filter!) but there is the odd occasion so it's worth knowing about the alternative.  The lens cap sounds useful as well.
