Forgive me for being late (again) someone mentioned Comet earlier in the thread and wondered what became of them. Comet was bought out by Guillow's in the late '90's and they seem to have no interest in re-releasing any of the Comet kits. The good news is many of the kits have been re-created by Penn Valley Hobby Center.

And, as mentioned earlier, many of the plans have found their way to Outerzone.
