Below are the ones available online to read.

I don't know why these are so damn hard to find, even indexed. Some of them rank among my favorites from the era, including:

SABRE (reprinted as issues 1 and 2 of the 1982 comic series)
NIGHT MUSIC ( reprinted, in 1985 comic, 1 and 2, in color)
DETECTIVES INC. (here reprinted in color, 1985, 2 issues)
THE PRICE (reprinted in color as DREADSTAR ANNUAL 1)
I AM COYOTE
THE ROCKETEER ( later version, published by IDW, with more material than Eclipse graphic novel.)
SILVERHEELS
PIGEONS FROM HELL
BROUGHT TO LIGHT

In the latter half, there's a bunch of them from the complere Eclipse list I've never seen, but many I'm familiar with are well worth checking out. Great art and stories, on a par with the best stuff from Marvel's graphic novel line.

They're not that rare, but the way they're categorized makes them harder to find than they should be. A good percentage of them in the latter haalf are uninteresting reprint material, in a black and white format (AIR FIGHTERS COMICS) that narrows popular appeal, very avant-garde, or just plain bad. The FLOYD FARLAND one I understand is early work by Chris Ware that apparently embarasses him, and he destroys every copy he can get his hands on.
