Sous vide - Anyone tried it?

I recently have started using this method of cooking with a crock pot, temperature controller, and Ziploc freezer bags. Berkshire pork chops came out perfectly cooked; tender, juicy, and way better than anything I've ever had except at The Admiral in Asheville where they were also prepared sous vide. Chicken breasts on the menu for tonight and rib-eye steaks next week. I would be most interested in hearing from any of you with any experiences using this method or about any great dishes you may have had prepared this way. pb
