I suspect that the difference is in subtle and in the BOM.

A ten dollar difference could be as simple as heat sink
or capacitor thermal specifications.   The heat sink could 
be invisible -- i.e. more/ thicker copper on the logic board

Contract manufacturers may also bring better quality practices
to the table.

Different internal filters, bearing seal or lubrication specifications 
may also apply.   I doubt that firmware is different.
