I don't know why advice on VK Classifieds re a scammer would be removed as inappropriate - such warnings would be a service.
I haven't been scammed for a while on the various sites, touch wood. I'm careful what I buy, who I buy from, and always want good pix.
I like descriptions like
"In like new condition" or
"Good condition for its age": and the pix show dings, scratches and dirty knobs
