I do that too when I know I'll need parts for a vacuum I havent even started restoration on yet. Because it likely wont exist anymore by the time I start! I was jumping up and down when someone listed a full set of Modern Hygiene canister attachments on eBay last year AND they were the correct ones for the model I had. I grabbed them very fast. All I need to find now is a hose (probably impossible) and I'll have a complete machine.Of course! I know what parts are hard to find and buy them as soon as they pop up on ebay.
