When it comes to online auctions, eBay is still the king. As of the writing of this article, eBay still averages about thirty million active online auction listings.

But growing discontent with eBay (remember the "seller strike" of a year ago?) has given rise to a new brand of eBay competitor. These new sites seek to lure new sellers with free listings, free photos, discounted final value fees and streamlined site navigation.

And a few are starting to make inroads in the once seemingly impenetrable eBay juggernaut. According to the website Powersellers Unite, at least three other sites have listings of over two million items each, and a handful of other sites are quickly gaining buyers and sellers.

If you are looking for an eBay alternative, here's a few sites you might want to check out:

* eBid - With just over two and a half million active listings, eBid is starting to gain traction as an eBay competitor. The site seems to have a strong international component, and does feature a nice variety of items. I found the site navigation simple and searching for items easy.

* Bonanzle - As of this writing, Bonanzle is trumpeting the fact that they now have over 100,000 registered users, and the site boasts over two million active listings. The site design is attractive, and sellers will appreciate the ability to quickly import items and feedback directly from their eBay listings. The site also allows sellers to give instant discounts and offer special sales called "bonanza's."

* eCrater - Focusing more on the store concept, eCrater offers over two million items in all categories. They promote themselves as a "100% free online marketplace" and site navigation seems quick and easy.
Items are offered for direct sale, as opposed to the auction format.

* CQOut - Based in the United Kingdom, this site is growing quickly with over one and a half million listings.
Like many of the eBay competitors, they offer free listings and seek to make selling as painless as possible.

* IOffer - IOffer claims to have thirty-five million items in all categories. The concept here is a little different; a seller lists a price and then buyers can "make an offer" which the buyer may accept or refuse. Sometimes having to make an offer and go back and forth with the seller makes things a little confusing, but the size of the site and variety of items does make it worth checking out. Like some of the other eBay competitors, IOffer also give sellers the chance to import their eBay listings and feedback.

There are many other sites currently trying to make inroads in the online auction marketplace, and the number of eBay competitors and eBay alternatives is sure to expand in the near future. Explore the links and check them out!
