Best Deal Portals out there? (For SF Class purposes)

Hi guys, I'm currently helping out as a TA in a Search Fund class starting in a few weeks, and we need a good deal portal for students to access deals and evaluate them for a class assignment. The site we used to use is retiring. I've checked out bizbuysell.com, dealstream and a bunch of others, but I'm looking for something that ideally has more information on its deals. Any recommendations?
