Careful about this. When I was provided a replacement 630 due to failure of the first, they started charging this multi-receiver fee. This despite my having shipped back the failed unit. "Oh, sorry, a keystroke error, they said...". Extended warranties are in same category as "extra undercoating" on a car: not necessary. Live on the edge of life and ignore all extended warranties.
