Auctions are 90% bad deals because you often end up with someone getting over excited and bidding more than the next buy me now price for the same product. But 10% of the time you get lucky, particularly if auctions end at odd time of the day. So I find it's worth throwing some bids, knowing that you should almost always lose. Ebay is best when you are not in a hurry and happy to wait for the right bargain.
I mean, an auction is something where you "win" by agreeing to pay more than anyone else. It's always going to be a bad deal for the buyer. The key with Ebay is to actually sell stuff on there too. If you're just a consumer you'll lose out on auctions in the long run.

I don't find auctions exciting or compelling, so I doubt I'd get overly excited about bidding. I'd just set a max bid (probably about half what I would expect to pay with "buy it now", to compensate for the extra delays and hassle involved with auctions) and call it good. If I'm outbid, I'd just do the straight purchase like I would have anyway.
The reason that unnoticed auctions might be worth me looking at is to expand the pool of possible sellers to buy from. Although if my bid makes the auction suddenly attract the attention of automated bidders/snipers, then there's no point to it for me. This might be a nonstarter.
I'll probably give it a try and see how it goes, though.
