All sound advice Big Ls!
I'd never use a third party's 'solicitor'/escrow arrangement for obvious reasons... The big difference between you and a scammer as you eloquently explain, is that you are an established dealer with a track record backed up with solid references and a reputation to protect - that's why prospects are prepared to 'buy blind'. I was referring to those who naively pay into an unverified account, without even the most basic due diligence. These people, I'm afraid to say, are asking for it.
