I bet Overp is the shitty buyer Your OP made perfect sense to me, TheEnd.
I, too, am a bit 
at the aggression being directed at you.
I'd just like to say, I was in a similar position, except I was a buyer. I wanted an activity gym for my baby. I normally always buy from the 'buy it now' items, as it's less hassle and I know I have the item I wish to purchase (I always, always pay for my purchases as soon as my purchase is confirmed).
Anyway, on this particular day, I looked at the available items up for auction and put a reasonable (very slightly less than what similar items seemed to be selling for) bid in, hoping I'd get a bargain. I did. I won the item for the opening bid and additional P&P (which was a few pounds over what other, similar items were going for). I was over the moon that I'd won and promptly paid.
Four days later, I received an email from the seller saying they'd had a flood and the item was no longer available. I responded saying I was sceptical, however, I'd accept the explanation, as I had no other choice and I'd expect my payment to be refunded, in full, directly. I actually had to open a case to get my money back!
Ebay is a bloody minefield and despite the above, I'd rather just ignore the feedback for the non performing seller than leave a neg. I'm just a bit soft like that, I suppose.
Glad you got it sorted and learned an invaluable lesson. I hope you make a killing on it, when you re-list.
