I used to use Accept eCheck Payments 2.0 module on my older 1.3.9h zen cart, and it worked very well for what I needed. Unfortunately I no longer have a copy of the original zip file and it is no longer listed in the plugins area. I was reading the php file from my older version and realized that it was once a osCommerce module, how easy is it to incorporate or convert the modules if I can get a copy of the updated osCommerce version?
