I bought joomlistings about a month ago and since then they have been just great. This component has really made my site very efficient and dynamic, but the thing that I like the moste is their Support, they have overreached my expectatives, even if the problem was not caused by them. They have contacted me morning and night just to try and fix a problem which was caused by me not by them, and still they guided me through the solution. This is really what I expect from a payed extension.
Joomlistings is the way to go if you want your site to run alone, or as controlled as you want, it has an oustanding felxibility.
I´m anxious to try the new 2.1.7 version, It can only get better!
