Well, Chuck, I should have payed attention to this. But at $5
purchase price I guess a 4000/200 is good enough. I just had
second thoughts before paying $200 for shipping this thing.
Now, suppose I could find a /300 packplane from a parts seller,
how could he tell the difference between the faster/wider and
the traditional Qbus one? Also, if that was clear, what accessory
parts should I make sure I also get, like special cables,
different power supply cables, mounting hardware, that sort of
stuff?

thanks,
-Gunther
