I was so excited about my recent trip to Bali that I used 4 guidebooks. Lonely planet was one of the most useful - it pointed out the tourist traps as well as the great spots. Many of the recommendations are more suitable for backpackers than mid range travelers, but the maps are excellent and the coverage of the entire island is good. Bali will not be the most beautiful place you've visited (it is still a third world country)but it will be the most interesting,especially if you work at understanding the culture. I found the Moon Travel Guide,Bali Handbook, published out of Emeryville California to be the best Bali book. It had the most descriptive narrative (over 300 pages) of Bali's culture, history and customs. However, it is not widely distributed, but is worth searching out.
