If it is not "Ships from amazon.com" and "Sold by amazon.com", I don't usually buy it. Sometimes I'll buy a "Ships from amazon.com" and "Sold by XYZ Corp", but only if I recognize "XYZ Corp" as a reputable firm. Customer ratings and reviews as a crowdsourced reputation mechanism is pretty unreliable. The Q&As are sometimes more informative.
