I did a little snooping on your transaction and see that you were a 0 rated seller. I can definitely say that a 0 rated seller trying to sell any electronics is going to be victim to a scammer. that buyer's rating is too high to block, alas you can only block negative rated folks.
How I started out on ebay was selling small things less than $5 to get my rating up to over a certain mark, cant remember the specific rating as it was so long ago, THEN I put up my "store" in total up to sell. I've never had an issue (where's some wood to knock on?). I do sell niche products that I hand make myself, or are drop shipped and are very specific, not in the electronics category so perhaps I am pretty safe. They are also in the $5-$20 range.
This makes me ponder if you had a history as a seller, say 20 or so, would they(the buyer and ebay) have treated you differently? I think so.
And would a 20 rating seller versus a 1000+rated seller also have different treatment?
Have any of you high rated sellers been duped and Ebay would not take your side?
I did miss a refund of my fees one time, I refunded the buyer and did not know I had to file a claim and by the time I had figured it out, it was past the claim time frame...
There is alot to learn and I still know one day I will likely get burned by any of my web selling avenues, but I've now sold online for 8 years with 100% success minus a couple of refunds I initiated.
I am so sorry for your situation, It is too bad you cannot figure out a clever way to get back to them. I do think that you could file a local police report, that sounds like a fair tactic.
I will be watching this post for more feedback and suggestions.
