Yeah, if you have an S.O. how would it feel if you were away from home from he/she/it for 6 months at a time? I think it would suck. Wait, change that. I know it would suck.
I'm all for making lots of money too, but how many actors have the same job for 9 years? Also consider that SG-1 would have been filmed in Hollywood if it weren't for the higher costs.
I'd hate to think how many shows RDA had had to pass up on too.
