As for the bidding, looks legit to me....
The first bidder put in a max bid of $700. When he did that e-bay would have listed it as $100. Next Guy comes along and puts in his max bid greater than $700. E-bay changes the $100 bid to $700 (first entry in history) and then the next guy is the current winning bidder with $710. The first guy then starts incrementing his high bid in an attempt to barely exceed the 2nd guy's bid. That's where you see $750, $775 and $795 bids. He finally exceeds the 2nd guy with the $795 bid. 3rd and 4th Guy come along and exceed 1st guys max bid successively. Although the date of the 4th guy who is currently winning is earlier, so he probably bid yesterday with a max bid and it kept getting bumped up but his max bid has held firm.
