I've bought well into six figures of equipment (not just audio) from individuals over the years and generally pay by wire/F-F/or other fee free method. Do your own diligence and know that you aren't dealing with a scammer. It's that easy. Of course losing "thousands" would not change my life. But I have saved many thousands in fees.
Don't let horror stories on the internet convince you that everyone is a scammer and you're not smart enough to tell the difference.
