Cheers for the suggestions chaps, will have to check some of these out.
I'm not really so into 'ghost' things though, I don't mind them... I prefer space themes/alien/freaky paranormal crap
I quite liked Stargate, but Atlantis had some terrible acting it - they took it too seriously, SG-1 was an OK sci-fi with humor, atlantis is a fairly crap sci-fi with bad acting!
