I just wonder if the other Cylon models we haven't seen will be introduced like Lucy Lawless, though. Where you won't find out until the end of an episode that a new character is a Cylon. Although I'm sure at least one more of the regular cast is a Cylon - otherwise it will be sort of the reverse of a Red Shirt crewman on the original Star Trek who beams down to the planet and is the first one to die.
Yeah, I agree. I thought the very same thing when Dean Stockwell first appeared. It will be interesting to see how they introduce further models...
How about this - the mother who reclaimed Casey is a Cylon, along with Casey.

She did come out of nowhere to find her, and what are the odds?
The whole way she just appeared was odd - and Gaius tested her when he had a working version of the Cylon detector, but wouldn't tell if she was Cylon or not to the 6 in his head.
I always suspected it - and the great thing is that if it is true, think how its going to mess with Col. Tigh? It could force him into a long trip to the dark side - really good potential there for fun
I was thinking the same thing. What a shock it would be to see Ellen appear again - man, what that would do to Saul...

And yes, her initial appearance was very suspicious, how she was "miraculously saved" during the initial attack and ended up on one of the surviving ships (what are the odds?) but that's one of the things I love about the show - it makes you think, second-guess yourself and be suspicious/clueless just like everyone on board.
If Ellen were indeed a Cylon, the neat piece of irony would be that she helped the Cylons on NC of her own will, essentially - it's not like she was programmed to betray them, she was actually acting of her own volition and love for Saul.
All this being said though, I do not think that Ellen is a Cylon. That would make the whole "relationship" with Brother Cavell just, well, weird...
