EDIT: Thanks for the feedback. I am only at 12 million for my whole build now so it sounds like I need gold more than anything :-)
I stole my SS for 265K so it seemed to me that applying the 5 million it would have cost for a crit SS would be better spent elsewhere for now. Eventually, I will upgrade it though. My resists aren't bad because of my intelligence; all 530+ after buff. I would like them to be around 600, but damage mitigation is not an issue for me at MP6 where I have been playing.
