The first (and as far as I'm concerned, only) season of E:FC is great. I picked up the season set the day of release, and marathonned in in just over a week.
Still need to go back through for the commentary tracks.
I showed a couple of episodes, the pilot and 'Sandoval's Run', to some friends of mine that like scifi but hadn't seen the series, and they really enjoyed it, too.
I already know not to worry about the rest of the series, but if you're one of those completionists, you're already too late - the third, fourth & fifth seasons seem to be out of print, and ya can pay a few hundred dollars for used copies on Amazon.
The first season, though, is well worth the thirty bucks Best Buy is chargin'.
