The fine folks at
Graphic Audio ( that's http://www.graphicaudio.net ) are who you want to check out. They have audio version of almost every Deathlands title and they are consistently excellent. They are available in multiple formats, including downloadable MP3 files, and each book has a free preview you can listen to first before buying. I highly recommend them, they are good people with an excellent product.
