Found a guide for "Lunar", (the original I think) for $20 locally and was wondering if that's a good price, or at least good enough to flip for a few bucks? It seems to be in good shape and is smaller than the normal books, more like comic-sized, but thicker obviously.

I don't own Lunar on any platform, but hope to someday, so this might just go into the collection.

LMK your opinions.
