Extension cords

Hello, I would like to be able to connect my 2 subs power cords, and my phono pre pc to my power conditioner, but in order to do it, i will need ext. cords of around 10 feet long, my question is, what would be my best bet as far as aquiring ext. cords to serve this purpose, could i go cheap at home depot and get acceptable results, or should i go another route. thanks in advance for any opinions.
