jsinger, although eBay isn't generally worth it for a lot of businesses, I wouldn't rule it out completely without testing. My previous business netted 6 figures from eBay alone back in 2004 as well as 2005. The products I was selling were extremely unique, had really high margins, and almost zero competition. eBay was a great way to promote my company and products to a massive audience base.
I also received a lot of customers who bought from my site directly after seeing my eBay listings. Again, my products had almost zero competition and this made eBay work in my case. I wouldn't tell people to not test eBay. But then again, I don't think people should rule out testing anything, because you just never know until you try.
