Don't know if this site was previously mentioned or not. It has some good listings under reviews. I added a couple of apps myself after a look there. Switchballs a free game & House & Home a decorating app.
Thanks for showing the love guys I hope my site is helping you find great playbook apps. I'm really excited with all these apps that are going to be coming out for the new phones and playbook. SEGA on the playbook who would have thought ???
