Hi David, thanks for all the good suggestions.
Actually, I couldn't have written them better...(looks like we have
similar experience...).

That's what I'm saying for a few weeks now...:-)  (but I feel I'm close)

Yup, no such things on eBay, and the list vendors haven't heard about
the European models.

Yep, agreed again. But what si that damn part?...:-O

Hehehe...don't worry my friend, we're not going to fall into another
argument like the one you were recently burned in...:-) :-)

Obviously you're pretty good, as is Leslie (OK, I'm not so bad either...).
No need to apologize for that...

All, good, standard practices that it seems we're all experienced
with. The problem is finding the needle in the haystack (the defective
