I wish Paramount would get off their arses and do those books you mentioned, but they seem reticent now - there's still no real defined Ent-E or Defiant book (Vulcantouch got me the DS9 tech manual before he died, but it's not much of a Defiant book).
You know, I just didn't even realize that Jackill was still making those books. I went to the website and thought, "There's new stuff coming out?" I haven't read a Jackill manual since high school, more than ten years ago. I might have to pick up the -E manual, and I really wish Pocket Books or whomever would put out some good material on the First Contact ships, Norway, Akira, Steamrunner, and Sabre. I know I might give my left and right arm to have gotten those ships in Micro Machine form.
