I have to agree that Ebay isn't the great marketplace it once was in the late 90's and early 2000's.
Everyone knows about it now. So, like that favorite music band you once loved, once everyone learns about it and it becomes popular, it loses value.
It used to be you could get great deals from Ebay using the old-style auctions. I often sniped from my cell phone, and made out okay.
Now, it's hard to even find scarce items or serious deals on anything. I agree the BIN auctions aren't so great. They're basically neck-in-neck with retail, so everything has become so homogeonous.
People are also more Internet savvy, these days, which is why Ebay shops -- places that sell your things on Ebay for you -- aren't quite the boon they used to be.
Craigslist may not be at the same level marketplace as Ebay, but there are no fees, and even no PayPal, which was bought by Ebay some years ago.
Craigslist is nice because you get more direct contact. It's best to leave your phone number so folks can actually talk with you. I always feel you can tell the true intentions of people by their voice via a quick phone call, as opposed to an inorganic email.
That said, I have several Ebay accounts, all of which have 100% feedback as both a buyer and seller, and only hop on to sell quick stuff anymore.
I may go with the store format and try to sell things on Craigs simultaneously (I'm moving cross country in about 6 weeks and need to get rid of things, so both sites may be the way to go.)
Back on track: Ebay is more of a commercial site than it used to be. These days, as I'm in school for a gaming degree, I mostly buy games of course, as well as books. Half.com and Amazon and Buy.com work best. I rarely find anything cheap on Ebay anymore.
