This might not be price inflating. I put up my SSK last night for $275 and it sold overnight...0 feedback buyer but he just paid the invoice so seems like he's a genuine buyer. Of course my price was lower than this SSK in Australia but there seems to be a disconnect from the Ebay pricing and the price of SSK's on GH.
On a side note, I don't use Ebay much, but oh god those fees are so heavy...
