C7 power cable for Blu-ray player?

I need to upgrade a power cable for my Onkyo BD-SP809 Blu-ray player, I still use the original throw-away cable, that's type C7, non-polarized. I don't want to spend more than $150 USD for Blu-ray player cable, hopefully even less if possible. The shorter, the better, around 1 meter or less if possible. And I must choose between those brands available to me.

Can I get a noticeable improvement in audio/video quality with $100-150 C7 power cable?
Do you have experience with C7 type of cable?
If your answer to both questions is YES, please recommend some.

Searching only among the brands and prices which I can get, I've found:

VooDoo Mojo

AudioQuest NRG-1 and NRG-1.5

Anyone familiar with these? AudioQuests got very positive comments on Audiogon. Any other?

THANKS!
