I’m from the UK & now live in France, Ihave purchased & sold many pieces of HiFi gear from & to the US, I haven’t had one single negative experience regarding the US, which makes it-no  more crooked than most Countries, in fact I would say it’s better than most others imho
Audiogon is becoming the hub for scammers.
In the past 12 years, Audiogon was a great resource for buying used Mcintosh Amps. Recently, it became the hub for scammers listing all kind of Mcintosh gears. I got scammed myself but Paypal and my bank caught it. Audiogon answer was be careful with some of our sellers( what a laughable comment). For now, I will not list or buy till Audiogon find a way to verify the new sellers. Too bad 👎…,,
