I live in Baton Rouge and have been working on the same question. Not sure which brand i'm going with yet but definitely looking at the ceramic tint as it doesn't impact radio, cell, etc. and typically doesn't look highly metallic. There is a Huper Optik tint place in Bossier City but i believe that's the closest. Formula One also has a great reputation and there is a place in Alexandria. Maybe someone closer to you in MS but don't know. In Baton Rouge, the most reputable spot is TNT and they sell SolarGuards ceramic. I think their rep is also very good but don't see it discussed on here as much. Price for my 4 door is $350-$400.
I'm also possibly interested in clearbra so let me know what's around. TNT does them in Baton Rouge so i'm gonna check it out.
