Alex,

As a Journey fan, I'd say you need the boxed set, and then Frontiers and Infinity to do a good job getting the best of their music. For less $, I'd recommend their Greatest Hits, but a lot of their stronger music isn't on their greatest hits.

You could get a lot of great music, and hear it live where Journey is best, by buying both of their Live CD's...Captured, and Greatest Hits. There is some duplication there however.
