I really like the design of this script.
The script is a nice base to start from.
It allows you to do exactly what you need to do.

Customizing the script is a totally different discussion point.
If the author of this script is willing to help you out with customizing the code for your needs, go for it.

Of course, a few small improvements can be made to the script.

I personally wish there was more granular control over the colors and fonts of this scripts but then, it would probably cost more.

One more thing to remember when purchasing this script is that this is both the Front end and Back end script so don't go complaining about it if you can't manage both.

Essentially, 2 people should manage this script.
