Which A+ Technician book do you use?

With so many books out there I am having a difficult time choosing which A+ book I should buy. I recently got my Security+ and am going for my A+ shortly. I would like a book that is more of a troubleshooter for fixing PC’s instead of a guide for the exam. I already have study material for the exam however a decent A+ PC troublshooting book would be good.

What do you recommend?
