I read this entire post and find the comments and ideas very helpful.
I want to offer my site as a great alternative to the others.

The site sales marketing model is via membership: with the following:
No fees for buyers
Low cost monthly sellers memberships
No final value fees
No commission fees
.25 cent "Featured Listing" fee
Image listing capability
Unlimited HTML listing creation
Auction, Buy it Now or Proxy sale capability
Internal credit system
After years of using ebay I created this site where buyers and sellers can do business safely without the "Big Brother" attitude hammering down on you!
Our motto! A basic online auction that won't rip you off!
Check it out and see if it works for you!
