It seems like if "Sunset" publishes it, it's worth having a look at. I liked this plan book a lot, it had a nice variety of floor plans. The illustrations were pleasant, and I would think a person would get a plan that was what they needed or close to it. It's fun to surf plans, and then alter them a bit if they're not quite the "perfect" plan.
I doubt there are very many plan books that have everything totally penciled out, since they really want you to buy their floor plans after you see the samples in the books. Nice book!
