I have not found another similar component that compares to JomRes. Once you become familiar with the basics, it is easy enough to configure JomRes the way you want.
Support is excellent. My only complaint is that you must update the component frequently, which is always a risk because any other components, plugins, modules or even your template may not be compatible with new versions. However, JomRes support has helped me through this kind of thing more than once, and there has always been a solution (normally it's finding and updating a badly behaving plugin).
Kudos to the developers and JomRes support!
