I'd be willing to bet money that none of the bidders were legit. It had to have just been random people that the seller knew and he asked them to bid it up.
I was bidding on one 2 days ago that sold for about $360 and one not too long ago went for about $270. Some of the beat up ones went for about $100 or so. I ended up getting this one yesterday for $165. A little more than I wanted to pay, but oh well. I'll let it go for the low, low price of $300 if anyone is interested.
