Lack of good, close-up high resolution images didn't help the seller's cause.
With better images that allowed buyers to 'inspect' the camera at a closer range and see every little ding, dent and scratch on it's surface it could have sold for much, much more.
Then there's the fact that the seller only accepted Paypal. Successful eBayers always accept as many payment methods as possible, it just looks better to the customer even if they intend to pay via Paypal anyway.
Lastly, ALLCAPS is something that to me always screams "scam" and I'm not comfortable bidding on items with all-caps descriptions, even if the seller is genuine - it can be impossible to tell if their account has been hijacked sometimes.
A lengthier and more descriptive description would have also helped, that goes without saying.
I think it's the 'little things' like that that really make a difference on eBay, after all you are pretty much taking your seller on trust so they more they do to reassure you that they're genuine and serious the more $$ you're willing to risk giving them.
