To be perfectly honest, a lot of the best science fiction and fantasy shows on now are currently coming out of the UK. Eureka is a great pick for the Syfy channel, but a lot of their current shows are not living up to the shows they have aired in the past decade (the Battlestar Galactica reboot, Farscape and others). There are many channels to catch reruns of older great science fiction shows (Star Trek and Quantum Leap reruns are always a sure bet).

If you can get your hands on the shows that the BBC and other UK channels have been airing, you are definitely better off. Doctor Who is currently running on the BBC, and it is has the record of being the longest-running science fiction show on television for a reason. It is a show about a time (and space) traveling alien who is a bit of a madman. He picks up humans, takes them with him and shows them the universe. It's full of adventure, comedy and fantastic sci-fi.

Other great UK options in the science fiction and fantasy realm are Merlin, Being Human, Misfits and Primeval. Life On Mars is over, but if you can download or grab a copy of that, it was easily one of the best science fiction shows ever written (do not bother with the US version--the concept of the show was completely ruined). It is a show about a cop from our time who gets hit by a car and wakes up in the 1970s. He can't tell if he's crazy, gone back in time, or in a coma and trying to wake up.

The ridiculously named SyFy Channel has two of my favorite sci-fi television shows right now. Eureka has actually been one of my favorite all-time shows because it combines a city that is populated almost entirely by scientists with a federal marshal who is technically the town sheriff. The show has quite a few great characters and it is really a comedy show with a lot of great science fiction mixed in.

Warehouse 13 is the other show that is great science fiction and it is also comedy bases though the show trots out a number of different gadgets that are used and have to be stopped by special secret service agents Pete & Mika every week. Those two shows are my favorite sci-fi programs at the moment.
