Thanks for all the responses. Yeah, I figured the general consensus would be to go for it, if I were single, it'd be a no brainer! Plus, with US government loaded with debt, the best days of aerospace is probably over.
However, wife just can't agree with longer hours and same level of pay. This job definitely isn't worth a divorce! Plus, if I go, we'll probably need to relocate closer to work in order to cut commute time. So the logical solution is more money! So, I turned down their initial offer and asked for more money..., now it'd be a matter of whether if they want me that badly! Although it is a startup venture, but I know they're pretty well funded. Fingers crossed.
