but I just don't get the attraction.

It's a way to easily find stuff you need. It's also a generational thing.
You're old and not expected to 'get it."


As a buyer, I want cancellation privilege not only before the sale,

You have that, it's called not bidding. Ebay is best for stuff you know you
want.



Even AFTER buying something, if I have a problem with it, I want the
option to return it to where I bought it for full credit.

You may have this option if you buy it from a store. Many avionics shops
now sell on Ebay and provide the same services as if you called them on the
phone and bought something. If you want this then email them and ask.
