Amtangee is relativly unknown globaly but is recommended by JTL, who offer a Shop System and a lot of e-commerce Software. There are therefor a lot of people who use Amtangee. Problemis, Amtangee is horrible. So most sooner or later want to leave it behind. It can export in CSV and VCard which i assume would make this easier. other then taht amtangee runs on a simply MySQL Server, so if all else fails, you can just grab the info using SQL.
