Re: Not New Canon stuff Hop..
There are collected format stuff from the Dark Horse years that Marvel reprints in a series of TPBs called Star Wars Legends Epic Collection. There are several series in it, The Rebellion, The Empire, The New Republic, The Old Republic, etc. They're probably 25-35 a piece and contain between 12-20 single issues a piece from the respective eras and material originally published under Dark Horse.
So you're looking for..
Marvel Star Wars Legends Epic Collection Rebellion vol 1, vol 2 etc
" " The Empire vol 1, vol 2 etc
You will pay up the butt to collect the original DH collected prints. Same with Dark Empire for a quality original DH printing. As Sev said it's the definitive early EU title with waves far beyond comics tho! Ever since Marvel acquired it ALL SW DH stuff soared.
DH did a whole Rogue Squadron series that ran for a long time also, I'm not entirely sure if Marvel is reprinting it in any of those Epic series yet though.
