I recently purchased my fourth copy of SSBBT because people keep "borrowing" it. I don't mind since the hardcovers are like 12 bucks on the Aasgaard co store and it's a good coffee table book.
And my mom bought BBRx after stealing my copy #2 of SSBBT, so I extra don't mind.
These are great books, and fun to read. I rate these 11 RPEs out of 10.
