If you have a gamecube or Wii you could get the ones on those. And there's always the used games section.
In Sacred Stones my favorite would have to be either L'arachel, Joshua, or Lute. They're all so quirky. And the Gerik's mercenary band is awsome too. I get crushes on video game characters a lot for some reason. I like have had crushes on all the FE bird laguz guys...except Ulki who is kind of demonic looking, and Nealuchi, but he isn't so bad, just super old
. And then there are other guys too.
Did you play through Eirika's story or Ephraims? Or both?
