I love watching this stuff. I call it trolling for a big fish.
When I see something that is obviously over priced I usually go,,,, Uffff! and move on.
There is a small green arbor press on ebay right now in the "vintage" reloading tools section. It has been on that site for better than a year. It is an arbor press that was bought out of Litton industries in Thousand Oaks CA. It even says Litton on it. The starting price was $349.95! it is worth $20 on a good day as it is nothing more than a Chinese 1/2T arbor press available at Harbor Freight for $29.95.
This guy knows damn good and well what this tool is worth. He is trolling for a fish to jump in his boat. Simple as that. Maybe someday he will get lucky.
I hope the listing fees from ebay eventually eat him alive.
Knowing what you are buying and what it is worth is key to operating in todays world. Ebay, Craigs List, and all of the others should require a big "Caveat Emptor" sign on every thing they list for sale.
This all holds true even when we are experiencing gouging like in most recent times.
You need to know what you are buying and what it is worth.
Patience is another point. I have found that if you "Must Have" something, you will probably get screwed when you buy it. I've done it ,,, you have too!
Not having to have something , or a take it or leave it attitude is how you get bargains.
Just relax and if you see somethng for a price you are willing to pay, buy it. If you don't feel you're getting screwed, then you aren't.
If you in fact did get screwed then it's on you, not them, for not knowing what you're buying and what it is worth.
Educate yourself before you buy anything. You'll save alot of money when you do.
