Query: Really good book!

Very complete book. Describes most groups, and the arthropods you are most likely to find. Not too technical, great for explaining to people what they are looking at. The 2 problems I can see with it, are the cost (although I do not mind paying for quality in the least, which is why I bought it and highly recommend it) and that being a general guide it sometimes does not go into as much depth as I would like. Still, I rate it as an awesome book!
