Since someone said The Laser's Edge has "Juggling 9 or Dropping 10" for only $5, I'd start with that one....it's one of my favorites, anyway. I'd go ahead and pick up "Blueprint of the World," too. They're both incredible CDs. After that, in order, I'd get "Break," "Blink of An Eye," then the others.
Don't get me wrong, though, any Enchant CD is a great CD. They're all good, which is why you see different recommendations from different people....some just resonate more with different people.
By the way, for the uninitiated, one of my favorite things about Enchant is their lyrics (and of course, the awesome vocal delivery). Check out the lyrics for "What to Say," (about a real person dying of a brain tumor...the singer's brother-in-law, IIRC), "My Gavel Hand," "The Thirst," or "My Enemy". Brilliant, emotionally-driven lyrics.
If you don't really know the lyrics of an Enchant song, you're missing half of the song, IMHO.
