There three auction companies in the area that I deal with. The "big guy", the "mid sized guy", and the "smaller guy".
I gave them these names based on the size and amount of auctions they handle. The best deals come from the "smaller guy", but it depends on what you are looking for.
You have to learn to watch the crowd as well as the auctioneer. I don't hear to well, so if there is something I want, I'm always "up front". These guys know that, and they know to watch for me. They also know that I'm cheap and that I know what I'm willing to bid on an item. I can however get things started for them on something slow. Once I hit that predetermined value in my head, I'm out!
Pasbuild,
Here's a link to that auction.
Hudsonville Fall Consignment AuctionThis is supposed to be the second biggest auction in the lower part of the state. This one is held twice a year. Because this is a consignment auction, they never have a full list of items until the day before and it can be hit or miss as to what is there. There will be TONS more then you find listed. The auction goes on through rain, sleet, snow, and shine! We have had all of that during one auction before. One of them had 7 auction rings selling at one time. Kind of makes it hard to keep an eye on things when 3 or 4 things you want are selling at the same time.

The biggest is the Pontiac Silver Dome auction. Have not yet had the chance to make that one.
