I think that you did very well... I have often had better luck on eBay over the years that with Amazon with phones, computers, drone components and DSLR lenses, etc... I use Amazon to figure out what the going price is and then see if I can do better on eBay.
Thanks. Ditto on the pricing experience.
It occurs to me that if I want to upgrade this little machine for wifey, I may be able to find a laptop with a damaged display very cheap, and plunder it for parts, then resell the motherboard & probably the processor....
