Query: Finding Parts is a Huge Hasssle

I've owned this Dyson for a couple of years. My toddlers popped off a section of the vacuum and have lost a tiny gasket. I spent two hours shopping online for replacement parts, trying to determine which part I needed from a tiny online diagram of the vacuum disassembled. Most of the OEM part sellers are overseas. I had a non-OEM part shipped from Sears at a cost of about $12. It is the wrong part and is not returnable. Now, I'm emailing eBay sellers trying to get this stupid $2 part so I can use this machine again. I'm just aggravated. While the machine works well, it is very, very heavy. It was also very expensive. Given the weight and the difficulty finding replacement parts, I would not purchase it again.
