I happened to notice that Amazon lists "The Amiga Years" as being in stock. I also noticed that it is being handled by a vendor calling itself "SuperBookDeals". It has quite a low feedback, with quite a number of complaints about book orders not being fulfilled. Be very careful if ordering. Is there another source for this book ?
