To echo Ian's comments, I am glad my big days of scanning eBay were done prior to the proliferation of douchebags that we see quite consistently these days. Not to say they weren't lurking in the shadows back then, Preludicious, Eakaz, and a few more, but no one had the balls back then to list a pair for a BIN of $4000. That's like waving your middle finger to the whole community in my book. No class.
BIN & Best Offer auctions have taken much of the excitement and potential out of ebay for me. I don't even look at them any more. I can realize their intention for the seller/buyer balance ... but they still suck.
God, I used to love sniping some poor sucker from Seattle in the wee hours of the Japanese night...
