FFIV was good, but it's one of those games that didn't stand the test of time too well. I like it purely for nostalgic purposes (was my first FF-- went back and played FFI later after playing II) because the story doesn't do much for you, it's very linear, and it just doesn't move you the same way VI. Don't get me wrong, it's a good game, just I would be surprised if you played that and said "this is it?"
And as I said, Anthologies isn't easy to find for a good price being that it's a PS1 title and a very good very sought after PS1 title. You might get lucky and find it used some place like Movie Trading Company (if you have places like those nera you) but I wouldn't count it.

Holy crap, apparantly I'm wrong.

Whhops, I forgot that Anthologies had FFV and FFVI while Chronicles had FFIV and Chrono Trigger.
