One that I would love to see, but never will because its caught in perpetual IP hell is ROM. Bill Mantlo took a licence for an admittedly crappy toy and turned it into something great.
This one isn't old at all, but I really want to see Wintermen finished properly and collected. It was easily one of my favourite comics before they started fucking with it just to get it finished in a smaller number of issues.
I blame Warren for getting me onto it in the first place.
Because I want to relive my childhood or something. I would like to see the I...Vampire series Hardbacked. Plus I would love a reprinting of Spider-Man vs Wolverine. I thought the story was great; Wolvie knowing Peter was Spider-Man, Peter killing Charlie by accident, and the end with him coming home and Mary Jane was waiting for him, he turns her away, she leaves but comes back and holds him. I think it's one of Jim Owsley's best pieces.
Plus I would love to see "showcase" reprintings of Superman and Batman family, just because I remember buying the doublesized issues for a quarter.
I like the Morrison Doom Patrol (just finished book six today), but I think Xombi is almost as good for how short a run it got (21 issues).
And I'm only one book shy of completing my run, but I'd like to see more people reading Shade, the Changing Man, so they need to do a Showcase or otherwise collect more than just the first half-year. Pete Milligan's the most underrated British invasion writer, and Chris Bachalo gets better with every installment.
@erudite_ogre: Sorry for the delay there, but it was extremely reasonable. For the basic binding service, Library charges about $19, including shipping. I ship the comics to them Media mail, which costs almost nothing. And the issues I send are usually ones that I found in dollar boxes, or had already compiled. So it's really incredibly cheap all around. I've had done:
Hellstorm: Prince of Lies Ellis's Marvel 2099 Hard Time Resurrection Man Sleeper Essential Vertigo: Swamp Thing Human Target
And at the binder right now:
Ellis's Excalibur (including Pryde and Wisdom) Fallen Angel v. 1 Sleeper (I gave the first away as a gift) All of Ellis's random early Marvel work through the Wolverine run
A couple of underrated gems that cry out for collections:
Teknophage (Tekno Comix/BIG Entertainment) Xombi (Milestone Media) - Actually, the complete run of Static and Icon wouldn't be too bad either. Fate of the Blade (Dreamwave) Johnny Double (The Vertigo mini) My Flesh Is Cool (Avatar Press) Night Raven (Alan Moore's run)
Also, I wouldn't mind seeing some of the more offbeat public domain Golden Age comics features reprinted, preferably with retouched coloring. Crimebuster, the original Daredevil, Boy King, Mister Risk, Yankee Longago, The Eye, Captain Battle, Madame Fatale, Airmail and Stampy, Speed Centaur, Hydroman and Rainbow Boy, K the Unknown/Black Owl... Because Golden Age crack deserves to be shared as widely as possible.
The Cowan Question series, although DC is in the process of releasing this. Millar/Morrison Aztek series, again, DC is releasing this series. Kirby- OMAC and Kamandi is affordable formats. Kirby - Machine Man and Strikeforce Morituri for the real comicbook geek in me.
