I've got no issues with the quality after market boards..
I have used them in a few of my machines - System 80 included.
Most - if not all are redesigned to overcome some faults / factory issues and with many parts becoming obsolete in some cases its the only option.
The other is cost. With the dollar being very good its even better value to buy these.
The original was $15 cheaper - I wanted the aftermarket anyway. And yeah - the dollar is nice!
$50US freight was a bitch though! (BAA)
