This is in no way a scam, just an example of how stupid and ill informed many ebay buyers are.
The guy has done everything right - a reasonable start price, not misled anyone and has even given a link to Harmony Central.
If people are stupid enough to pay over the odds for something they could buy NEW for less, surely that is their problem, not the honest joe seller?
A bit unfair to put him up here as a scammer I think.
