1. They have rolled out many new revisions that have taken it from good two years ago to truly great today.
2. I have needed support three times for minor issues, and they responded and fixed the problem within 24 hours.
3. They have a great library of plugins and add-ons and they keep adding to them.
4. For all that you get the price is VERY good.
If you are going to be building real estate websites, I would go for the developers pack, it comes with everything, but your money will be well spent on the real estate pro component as well (many of the plugins are free or very inexpensive.)
