**Notes:
You eventually get  to know when a  board is made by PC  Chips just by
looking at it.
 
Here is a test:
1.  No manufacture name, or one of the above.
2.  If the board has a lots of components that sound like a well known 
    part but aren't the well known part. i.e. 'HX Pro' instead of 
    '430HX'
3a. A really good feature set where you think, that's exactly what I'm 
    looking for.
 b. The features don't really work as intended. 
4.  The price is fantastic.
5.  Its disappointing on closer examination.

PC Chips is  renowned for making crap products. Some  are actually not
too bad, they're no worse than  your average brand. However some are a
nightmare either by design or  just poorly made. Fake components glued
on is not  uncommon. Fake labels over other components.  PCB's so thin
they require low insertion force ISA connectors, every trick to save a
few $.
