The main difference between the two you linked is the less expensive ones (Amazon) are PCB mount and the more expensive ones (eBay) are chassis mount. The common thread is they are both ceramic with gold plated contacts which is nice.
What is the project?
Oops! I'm late. Also I was wrong they are not both ceramic, the Amazon ones are and the eBay ones are teflon. I have never had any gear with teflon sockets.
