Here's the truth dude. I've been to more auctions than you can imagine - storage auctions, coin auctions, antique auctions, surplus govt merchandise auctions, customs auctions, repossessed car auctions, bankruptcy auctions, etc. YOU'VE GOT TO KNOW WHAT YOU'RE BUYING AND WHERE YOU'RE GOING TO SELL IT BEFORE YOU BID OR YOU'RE GOING TO LOSE YOUR ASS.
Almost every auction you attend, there will be some amateurs (aka suckers) with wads of cash and dreams of making big $$ and they will overbid things way beyond the point where it makes sense. Auctions are a great way to SELL stuff, not a great way to BUY stuff. I remember going to a gov't auction once and there was a nice Mercedes (supposedly seized by DEA). The car sold for over retail blue book. I've seen that happen many many times.
I've only been to a few storage auctions, and remember the units were basically total junk. Why would anyone lose a storage unit with $5K or $10K worth of stuff in it for a lousy few months rent? The units that do go to auction are full of crap; they've removed the valuables. Those TV shows are pure fantasy.
