Another lesson about ebay: Don't ever ship something to an address other than the one ebay has. My brother sold his phone and the guy asked him to ship it to "his daughter's house for a present". Turns out the account had been hacked and now he had just sent his phone to a scammer.
The last horror story i have: The same brother sold an iphone on ebay and the guy claimed it came with the screen cracked. Ebay sided with him on the return and my brother received a letter in return with nothing in it. Fortunately for him that time, ebay just let him keep the money and the scammer keep the phone (albeit, after 2 hours of arguing with their customer service).
TLDR: I've had way too terrible experiences on ebay to ever use them again.
So not only do you have to worry about scammers, you have to deal with a market for lemons [1]. (Quite ironic now that I think about it as that is one of my favorite economic articles)

The company I left last year sells the bulk of their products on Amazon, and maybe 1/4th of their inventory (same type of products) is listed on eBay. Amazon sales are relatively smooth with much less friction per sale than eBay. It's gotten better since they went with a sales aggregator service, but they still barely break even on eBay as opposed to Amazon and physical storefront sales, when they figure in labor and time costs. When I worked there the sales personnel were able to list five or six items on Amazon in the time it took to list one item on eBay.
eBay really doesn't make sense for a larger business unless they have thousands of the exact same, new sealed merchandise, and that tends to be the cheap mass produced garbage that you find on wish.com and similar sites. The small to mid closeouts wholesaler doesn't have a place on the site anymore, which is why many are moving to Amazon. Unfortunately, as this article points out, scammy buyers are just as much a problem there.
As things get more expensive on eBay, you become a bigger target for scammers and stand to lose much more, so it becomes a terrible option both because of how many scammers there are and their policy of screwing over sellers. Also the more expensive it is the more likely I'll be able to move it on craigslist which is a sure thing.
I haven't sold on eBay for ages. There's very little I want to sell that is worth enough to go through the hassle though I'm not sure there are generally good alternatives. (For used photo gear, I'd use one of the online stores. I won't get as much but there's much less risk and hassle.)
