Looking for a new Sci-Fi show?

With Battlestar Galactica on hiatus and my tolerance for re-re-rewatching star trek gone, I'm looking for a new good Sci-Fi show to get hooked on for the summer on DVD...Babylon 5 and Stargate SG1 seem to be the other powerhouse scifi shows around, anyone got a suggestion for a good scifi show for a discriminating taste (ie., no campiness or cheesiness)?
