I bought the collections they put out a few years ago (Time Travel, Klingons, Q, and Borg, in particular) and that has tided me over. The thing about TNG is that the majority of the show was ruined with whiny bullshit (i.e., anything having personally to do with Troi, Picard, and the Crushers) with pieces of hey-awesome sprinkled haphazardly in the mix. Stuff dealing with Riker (the TNG version of Captain Kirk), Data, and Worf were fun, and the Q eps were my favorites.
