Tom - What a good idea. I am sure a lot of us use a upright for carpets & canister for everything else. If I could make one suggestion though....why not make it a upright & powerteam canister instead of straight suction canister? Sure, they are good, but the one area a straight suction falls behind in is being able to clean under low surfaces effectively. A powerteam canister has the advantage there since it's powerhead can get under low furniture & still groom & clean as well as a upright.
I don't have any pictures, but I used to use my Simplicity Gusto or a Electrolux canister with my Royal Metal upright or my Kenmore Intuition upright for a cleaning team.
