With Mosets we had things up and running right away. In addition we purchased the new Kinabalu template which further improves the already good aesthetics.
The private forum support is excellent with detailed and easy to understand solutions given.
Like other directories this one does not come with a payment system built in. However there are third party solutions and we had this integrated in no time.
The only gripe we have is the way category selection is handled from the frontend but I understand from the developer that this is being re-worked along with some other nice features in the pipeline. It's not a big deal but can be a little confusing.
If you're looking for a professional edge to your directory and want something that looks great and works right away then this is your choice. There is a cost but frankly for us the time saved not having to hack the code is well worth it.
