If you like Fear Factory you'll like Cynic since FF pretty much "borrowed" their sound from them.
Some industiral stuff:
Einstürzende Neubauten
Throbbing Gristle
Thaw
I'm not big on that stuff, since I'm more of a hardcore/metal guy.
If you like Moonspell, you'll like mid-nineties Tiamat, which means you'll dig on Opeth, and then Edge of Sanity, etc. Just takes one band and some searching and you'll come on to a whole wealth of music.
I run a tiny music review site and I can shoot you a link through an e-mail or whatever. I feel like such a wiener linking it directly on the boards.
