Per Red Green:
$3500? !! When was that?

Bought a Rainbow somewhere in the 1990 timeframe. 700-800 range I think.

That works.... sort of...

$900 in 1990 is about $1,600 in 2014 dollars per

OK.... only half.... but I am guessing the Rainbow door-to-door business
model is around extracting the highest price the sales person can.
