After reading everyone's helpful posts, you guys have convinced me and I've decided to go with the Factory Service Manual.

Called Toyota Distribution Center (thanks Dandeman) and was quoted as follows (Gulp!):
Volume 1 - $66.80
Volume 2 - $118.74
Electrical - $47.09

Ouch!! I couldn't believe the prices!...I even asked the woman for clarification.

So it looks like I'll be doing some serious hunting for used ones. But until then I'll be making use of the great maintenance articles here at 4x4wire.com.

Thanks to everyone for helping out a newbie...I think I'm going to enjoy this forum.
