Query: Top of the Line on Living in Costa Rica

As far as I'm concerned Van Rheenen's book is the source. Not only did it give me information on all aspects of moving to Costa Rica, it was so elegantly written, I kind of couldn't put it down. Pretty wild for a book with so much practical info. Glad to see all the up-to-date info on new and available condo opportunities. Also, found the profiles of people who have traveled this road before extremely useful and interesting. It's an insider's guide, a toolbox, a great source of reference and a good read all packed into one. I'm giving it to all my friends for xmas!
