Yes, definitely. DuQuette closely adheres to the BoT but is a much easier read. Of course, it doesn't replace the BoT but it's good as a starter, imo. I.e., the book elaborates things the BoT touches and gives background information.
I got a new copy for $10 as well as an older print of The Book Of Thoth, I think 1974 in Like New condition which doesn't really matter to me that much because I have a feeling I'll be breaking the spine reading it! Still haven't received my Thoth Tarot deck yet but I'm spending this time getting the room ready for it when it comes.
