@therflu -- you can find audiobooks of Philip K. Dick's novels at http://Audible.com. I just did a quick search there on their website, and they've got:
1. Do Androids Dream of Electric Sheep
2. A Scanner Darkly
3. Paycheck
4. Martian Time-Slip
5. The Golden Man
6. Galactic Pot Healer
7. Minority Report and other stories
http://audible.com also has an ongoing promo where you can sign-up for a 14-day free trial. As part of the trial, you can download (and keep) any of the books they have, with no obligation to sign up.
Just go to http://audible.com/grammar or http://audible.com/twit -- both of those are promo links that have the 14-day free trial offer. Hope that helps.
