How to get information on foreclosure listings?

[John Buchanan]

I've spent a considerable amount of time trying to find a site (sites) that either you can sign up to receive upcoming foreclosure auctions or at least gain access to a posted online list of auctions.  I've been able to find a couple sites by real estate attorneys but its fragmented at best.

Is there a website or service that offers this info?  (did a realtytrac subscription for a while which seemed like a waste of money b/c the info was either posted after the auction, or not at all).

thanks
