I like some key episodes so I might get a best of box set or something.

They have been releasing popular episodes in separate packaging, if that floats your boat. They put Best of Both Worlds Pts I and II on a single disc, Redemption I & II on another release and Unification pts 1 & 2 will be coming next. That along with the sampler disc that came out before they released the season sets that includes Encounter at Farpoint, The Inner Light, and Sins of the Father... There's quite the best-of collection right there.
