Some comments on new appliances. Approx 6-8 years ago, IBM Australia shipped tens of thousands of brand new PC's and monitors where some power cables were wired the wrong way. To add insult to injury, there was no distinction between good and bad. IBM conducted a huge recall and for teh big corporate clients, they employed sparkies to test every cable and apply red insulation tape near the plug if it passed.
The company I worked for had just received 5000 brand new PC's and monitors!
