Best Foreclosure Listing Site

[Dave Poirier]

Hi Folks,
Two questions:
Can someone recommend a good site for a detailed foreclosure listing? I scan Zillow all the time, but I would like to have a more refined search and more pictures. I understand I will pay for access, I just want to spend my money wisely.
2) Is a local realtor the best way for me to get information on properties with good margins? I am looking to do my first flip and want to be careful and profitable.

Thank you for reading and posting.
