I have a few friends who went to Ari Ben. They loved it and got hired at regionals as soon as they were finished building multi there. THis place sells bulk multi time so you will certainly get a lot working there as an MEI.
American Flyers is not a good place to work! ATP's school in Jacksonville Florida one of their better ones. They have nice new airplanes at most of their locations now though I believe.
Here's another suggestion. Try Sierra Academy in California. You can get an F-1 from EmbryRiddle and work on a bachelor's at their east bay campus. This allows you to work at Sierra or one of the other flight schools in the bay area.
