I came across a few sites, gov-auction and governmentauction and I was wondering if anyone ever screwed around with either of those sites. They are claiming some serious savings.

I was wondering why an auction wouldnt naturally end itself at the market price? If I can sell a ring on ebay for 1000 dollars, how would I be able to buy it at an auction at anything but 1000 dollars? Doesn't make sense to me.

Any input? Anyone used these or similar sites? Are there free sources for these types of auctions? I am specifically interested in a motorcycle.
