I've listed a number of Gundam Wing doujinshi for sale in this entry at my journal. Most are yaoi, mainly 2x1 or 1x2. The list includes doujinshi from circles such as Atumi Anikees, Degital Papa, Finder-W, IHATOV-honpo, Melt Down, Nattsu, Ringo-Zaidan, and Vespa, among others. This is only the first batch to be listed; more will follow over the coming week(s). I'll be listing a number of The Sentinel and Stargate SG-1 slash fanzines soon as well.
