Legion of Super-heroes collections

As I've said previously, I'm in a phase of being very curious and interested in silver and bronze age DC comics. I never bought any of these when I was growing up and my first "real" exposure to DC was when John Byrne left Marvel to join DC and reboot Superman.

So all this stuff is new to me.

One series that keeps coming up on the DC archives message boards is LOSH and there is a Silver Age Omnibus of their early adventures due to be released in August which is on my wishlist. In the discussions these two collections were recommended as the best stories and as it will take years for the omnibus series to reach these issues I decided to pick up the trades whilst they were still available and not out-of-print. 

"The Darkness Saga" Collects Legion of Super-Heroes #284-296 and Annual #1 and "The Curse" collects Collects Legion of Super-Heroes #297-313 and Annual #2 so these collect a considerable number of issues. 

My plan is to get the omnibus edition and the brand new collection (SUPERBOY AND THE LEGION OF SUPER-HEROES VOL. Collects issues #234-245.) which will give me plenty to read and hopefully an understanding of what made the Legion so popular with DC fans.
