Can any one recommend the best sign re texture mod available that they use thanks

The only one I use:http://tesnexus.com/downloads/file.php?id=25314

thanks does it also change roads signs to or do I need a different mod for taht one?

Shop signs only, so you'll need to find a separate road signs replacer as well.

ok thanks maybe weathered signs i have seen that mod don't know if anyone likes it?

I use http://tesnexus.com/downloads/file.php?id=9498 first, then Unique Signs over that.

http://devnull.sweetdanger.net/obliviontextureoverhaul.html, The Oblivion Texture Overhaul, has links to all of these mods, and pictures of most of them. Why don't you look at the pictures and decide for yourself which ones you want?
