These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Keep Circulating the Tapes: Zenith has been out of print for almost twenty years, and, because of complicated legal issues surrounding the copyrights, will probably stay that way for a while. The original printings of the trade paperback collections currently go up for hundreds of dollars on Internet auction sites (the original issues of 2000 A.D. are somewhat cheaper)
Although as of May 2013, 2000AD have announced that they will finally be reprinting Zenith! Only 100,000 copies will be done however.
Phase I is currently available from online retailers as an e-comic, with Phase II to follow in December.
