I wouldn't go so far as demanding only salary because it kind of implies that you are certain that the startup will go bust rather than _might go bust_. However, I definitely prefer as competitive salary as possible; I don't know about the rest of the country but working long hours in SF gets expensive (apartments, eating out, laundry services etc).
