What Legion of Superheroes trade should I get?

[Flashpoint]

I like the run where superman goes to the future and found out there isnt a yellow sun anymore and people are educated into hating aliens

Another one of my favorites as well. Here's the cover to the collection which is still in print...

I say get Superman and the Legion of Superheroes. Just for Gary Frank's pretty drawings.

I second this.

Really great story, with lovely art. Worth every pretty penny, in my mind.

"The Curse" has LoSHv2 307 to 313. It's right after the uber-famous Great Darkness Saga. It's a good place to start because there are numerous story arcs that feature the entir Legion membership, plus you'll get to visit the Legion Academy, know more about Durla, have a cosmic threat in Omen. It is, together with Great Darkness, vintage Levitz-Giffen. Just a great read.
