After trying several other components to create a custom database, I finally found SOBI2. It's very customizable, and did everything I needed. Haven't had even a hiccup. Great job guys!

SOBI2 is the most adaptive, the fastest, the most usable and tweakable directory extension for Joomla.
I use it for a business site I have.
I love the templating system within it. Very easy to adapt and integrate it to your website. The code is valid XHTML which I have tested and run in almost all popular browsers. Overall I have to say this script impressed me, and is the best free script I have found.

I use sobi for 2 years and every time when I had a problem I could find a solution on the sobi-forum, where a great community and the developers can help you immediately or at the latest within 1-2 days. Just great!

Installed, configured and ran just as advertised. These guys did a wonderful job. Enough Superlatives? Not Yet!

Sobi2, is most probobly one of the best directory style components out there at the moment. Perfect for any category based listings system, such as yellow pages style directories. The ability to have an unlimited number of categories is fantastic.
I would highly reccomend this component to anyone wanting to start a business directory.

I installed Sobi2 on my webserver and bought the Radius Search Plugin from Mr. Suski. It is easy to install and fullfills all of my requirements. More important is the service provided to sobi2 clients. You may contact Mr. Suski and he will provide you with competent and quick solutions.
Waiting for further releases of Sobi2.

Almost all of the reviews are 5 stars. You simply can't find a better component than SOBI2.
Great features, easy customization, mega support, and they are always working on a new version. Next release is going to be amazing.
Ease of setup,installation was a breeze, very rich in features, better than expected!
