Doug mentioned something to me about an SAP when I was talking to him about Electroluxes, but he told me there were two economy machines produced in Canada during the AP series production: The AP (economy, non-automatic, no cord winder, straight suction version of the AP100), and the SAP, which is also non-automatic, no cord winder, and straight suction version of the AP280. I'm not sure if there was an economy version of the AP200.
Chris, if I find any APs around here in the city, I'll let you know.
