polyglot: I spoke with them today and they're happy to replace it. Already have another one on the way. Should be the end of the story (cross fingers).
CGW: The 558 is a little more than I want to pay at the moment. I've got a Minolta Flash Meter III that works just fine, except a slider has come off and changing between ambient and flash requires a sharp object! But it hasn't given me problems. Was hoping the "upgrade" would be just as good. Hopefully I find a dry one. Thanks.
