This is an EBAY seller we're talking about here. In the subconscious mind of the seller, solidpro already got that "refund": $1,000 (seller's desired selling price) - $470 (actually selling price) = $530 fried board discount
It is true that the auction in question says "Good Working Condition." In fact it says that more than once in the listing. But when we buyers obtain what we think is a good deal, we often tell ourselves, "well it's such a good deal, and since I have parts to repair it anyway, no use making a stink about it." The seller then gets off the hook and goes back to subtle sales deception. This is how EBAY works. I don't like it. But it's been my experience (as a buyer and EBAY window-shopper) for the last several years. Mac128 earlier commented about this being "a steal." And on some level, yes, the word "steal" is appropriate here. There's always a catch.
