I'm almost all-audio, and I LOVED Steven Webber's IT, and I love Insomnia (who?? can't remember) and once I get used to him each time, I love SK himself reading Bag of Bones - because I know everything is pronounced right and the author knows how to tell his story VERY well!! I like all the Frank Muller books and think George Guidell did a decent job of picking up, though he doesn't have that awesome Eddie Dean voice that Muller has - ah, well.
One more plug for my biggest audio-book peeve, though - Under the Dome - HORRIBLE!!! WISH he'd get somebody else to re-do it.
Ooooh, SK read the Gunslinger? That must be the original version? I read that first when I was real young, 12 or 13, and then again when Wolves came out, and realized there were all these tie-ins - then I went back and got my mom's copy of the book that I Had read as a kid and realized it was all changed! So that was fun, but I'd love to listen to SK read the original version!!
