I have been delighted with eBid both as a seller and a buyer. I've been there almost four years and I have never had a bad experience.
The site is growing rapidly, management is careful to screen out and control dishonest sellers AND buyers, only one account per address (keeps the dodgy people out), no duplicate listings (so I don't have to plow through pages of junk to find what I'm looking for), many payment options, worldwide exposure.
I have noticed that some of the people giving the site bad reviews did not follow the proper procedures to get help. I also know that some of these problems will not be handled by any other auction site. Try getting help on eBay if a buyer rips you off! Buyers always have recourse (they can get their money back).
