I am building this PC and recently...the price on everything skyrocketed. I need to find a good power supply for it, I thought 500W would suffice, but I've been told that If I ever plan on Crossfire, I need 700W+. Do I really need it? What inexpensive power supply can I buy without sacrificing quality?
~Here's what I have. I have already had shipped case, mobo, and disk reader.

Yes, you need more than 500w for SLI.

The one on your list will probably work, but I would go with a little more headroom for about the same money:

Nice, quick response...Thanks for answering my question and thanks for giving me that Corsair suggestion, it's perfect for what I'm thinking of.
