My client needed to accept event registrations for and wanted to accept both credit card payments and mail in payments. I investigated the options and decided on RegPro because of the fact that it didn't require joomla registrations and I liked the look of it. The install was quite simple - and I am not technical at all. When setting up payment options I ran into a snag (my error) and received a quick response to my support tickets. I have since used RegPro on two additional sites. I've been pleased with the ease of upgrading and the new features added like discounted admissions and the attractive calendar. I highly recommend this product.
