Is Power distribution unit (PDU) important for UPS

I went through APC frequently asked questions link :- http://ift.tt/1uBCGeK Here APC recommends against the use of any surge protector, power strip or extension cord being plugged into the output of a UPS. I also red the articale at Wikipedia :- http://ift.tt/WW7qDF where it is said not to use a surge protected power strip with a UPS.



I am using a power strip on which I have plugged in everything my laptop, modem, router as well as my whole desktop and it's peripherals are plugged in to it. Is it really necessary to use a "power distribution unit" (PDU) with a UPS or an ordinary power strip the one I am using now is fine.



Do all cheap power strips come with some protection which hinders operation of UPS. Mine has a glowing led circuit breaker switch.



I am asking this because I have spent a lot of money importing a very nice pure sine wave UPS from the UK to India. What should I do. Should I buy a PDU unit. Even the first in the lowest range from Cyber Power is costing an expensive $145.63.
