I got AEC before the change to commercial. However, I had problems getting it working properly with some extensions. After a bad experience with one of the extension developers giving me the runaround for weeks and no support, I decided to take a gamble and pay for the support for troubleshooting. It was money well spent. In little time, David and Jake had it fixed for me. Any issue, even templating clashes with the program I presented to them, they got it done! What a breath of fresh air. I would not hesitate recommending to you to use their paid support for any integration problems you are having with this component. It is well worth it, not to mention the component itself is fabulous. I am glad they moved to commercial because I want to see this membership payment extension around for the long haul. Great job, great extension, very pleased.
