What you are paying for is the ability to "re-act quickly" and handle a large 
spike.  A cheap surge supressor will not re-act quickly.  It uses a circuit 
breaker to shunt the spike.  Also as the load increases, it is harder to 
develop a quick a dirty (read that cheap) solution to protect.  Thus it is 
almost impossible to get a cheap surge protector for a DN10000.
