Passed the PWO-100 first try!
It was surprisingly easy...
1. Radio Frequencies Technologies 100%
2. 802.11 Regulations and Standards 80% <--- ::doh!::

3. 802.11 Protocols and Devices 100%
4. 802.11 Network Implementation 100%
5. 802.11 Network Security 100%
6. 802.11 RF Site Surveying 100%
All in all 97% overall.

I used a used Sybex book (copyright 2006) and study materials and practice tests. All in all, using the Sybex book alone I probably would have scored about an 80-85%. Life experience also helped, as the three years of configuration and testing evaluation of various SOHO wireless technologies paid off here...
Next is the CWSP. Anyone know what is the best study guide for the CWSP?
