Even more frustrating, who are these people that hit BIN then don't pay?!? I can understand throwing a bid on something thinking you'll get outbid and that doesn't happen, but BIN/OBO is a completely different ballgame.
In a similar vein - why is the "require immediate payment with BIN" not a default when selling?
And how come eBay never has a problem remembering that I'll accept returns with a 10% restocking fee, but loses its memory on my bidder requirements each time I make a new listing?
Also, I have gone BIN or BIN/OBO on just about every item lately, and don't think I'm going back to auction style again anytime soon (especially now that I've got the instant payment thing figured out). Over the past ten days, I have listed about 90 items at prices I feel happy about, and have sold around 50. Besides a few random non-payers and other hiccups, it's been great - things are slowing down a bit now, so I may adjust prices down if sales taper off pretty much completely. For my money is a much better experience than auction style listings - people don't forget to bid or don't get pulled away from their computer, rather they see it, want it, buy it, pay for it, I ship next day, everyone wins.
