I like my Thermaltake 420W and my dads Thermaltake 480W is great as well. Silent and very unlikely to be deadly to other components :Q

Fortron/Sparkle (FSP Group), Enermax, and Antec are all good. There are also some others that I can't recall at the moment.
I like my new Fortron 350W because it uses a manu-matic 120mm fan (temp controlled + adjustable potentiometer) that can move significant air at lower (less noisy) speeds, and still crank it when you feel like it to exhaust a lot of air.
I liked my Antec True-Power 330W because it had a "fans only" output for case fans that was tied to its internal fans' temp control. It worked well.

I would suggest going with a 400watt one, 560 seems to be alot of overkill, unless you're going to be running 6 ide hd's, 4 optical, 2 sata, dual cpu, all ram slot and all pci slots occupied, 4 usb devices running solely off the computer, and a bunch of fans and cathodes/lights etc.
EDIT: Maybe if you tell us your specs we could guide you better. I have 2 ide hd's, 2 optical, 3 pci slots used, one ram slot, one amd cpu (single cpu mb), floppy, 2 fans, and 2 usb devices (only one of which uses the comp for power, zip drive) running very well on a Antec True 330. I know you said you want 5xx range, but just offering my 2 cents.
