I got one yesterday in the mail. Haven't filled it out yet. Today in the mail I received a post card from the same company asking why I haven't filled it out yet and a phone number to call to get another one if I lost the old one. 
I just re-read the original survey and they must be targeting 400 recent buyers as I have bought both a 650 and 400 and it only says the 400 is the reason for the survey.
