I bought an ebook copy for under $5, and I like it so far. I haven't done any of the experiments, but I will and I will do them all, partly because my GF wants to do them with me
I'll post about any experiences with them. I'm confident things will happen, yet that's just how I am anyway
(I also was here before the crash, went by kentauros then, so I'm a new-used newbie.)
