What can be said this has to be the most used component on Joomla. If not a very close second :) The community is great, the dev team actually continues to work hard on the project and making changes. I sure hope Joomla is smart enough to change the GPL otherwise we will loose a wonderful component soon.
Oh yeah and its FREE what else can I say!

I have played with this component on and off for some time. The latest version is great. Added a couple of thing including the Alpha Index which on a larger directory I think is important. The Captcha code is handy too. The admin is also greatly improved.

I finally took the moment to register myself here, only to review and rate Sobi2. In the beginning i was lost with this component, so many options!! Taking a moment to read the Sobi2 Wiki, and with the great and fast help of the people (neo and trinity) of the Sobi forum..i got the layout exactly that i needed..this component is much more than some company index..im using it for an music album section! This component is indeed one of the most professional extensions for free! You guys are doing a great job..two thumbs up!!

I just wondering why this extension is not a editors pick.
This is the best extension I ever seen. And not just only this exetnsion is great. The support is much better as many commercial products have. Even if You have problems with SOBI2, you will have the solution for this problem in less than 24 hours.
Thank you very much.

I've used SOBI2 before for the basic business indexing purpose it was built for, and it works great out of the box. There are plenty of settings to tweak and adjust to get your site running exactly how you need.

It's simple the best directory component available.
If you want a online directory site, then this is the one to use. It is very simple and fast to install. The support in sisiu forum is really great. Since the RC 2.8.0 this extension has all featured which an directory really need: search in categories, check boxes group with multiple selection, and search in categories. Thanks an Trinity and Neo :-)

I think my title says it all, this really is the BEST component out there, and I have used many. Not only is the component easy to install, it is also easy to use, easy to customise, and to top it all off - and this is why this is the BEST - it has Excellent support from Trinity and Neo, second to none.
