Foreclosure websites opinions

Hi folks - I wanted to ask anyone out there give me their opinion on the various websites offering foreclosure sales listings. Of course they all want a fee for this service, either upfront to join for X amount of days or for the details of any specific listing. Are these worth paying for? Do they have information that I could not source elsewhere?
An example: http://www.hudbox.com/ ( hud and foreclosure listings)

Any others? Any that you all really like?

The ones I’ve tried are not very timely with the data. However, I’ve found going to www.firstpreston.com (HUD homes) and www.fanniemae.com is a good source for REO’s
