Early PC editions get a bad rap because of the recent (last 7-10 years) money grab by organizations printing multiple PCs and selling them at market value vs. issue price. DT PCs (especially I, II, and III) are rare and having a complete set is difficult to attain. A complete set of Publisher Copies is much harder to find than a numbered set. As Rabbit Trick alluded above, there are not many complete sets in existence. My guess is that there are 5-7 in the world...and they would most assuredly sell for more than a complete numbered set.
