Absolutely the best addon in my list. Does everything you need for an economic system with loads of customizable options in each option. Support is top notch. The price of this addon is worth the support alone.
Fantastic addon, and as always, the support is top notch. I really would recommend this any day. It can be a bit tricky to set everything up correctly but the developer will easily answer any questions and Dragontech actually listens to advice. A+ addon and support!
