What's your income worth to you?
callmeed: Well, if the cost of living at the new location is less than where you are now, that offsets the pay loss some.I guess my advice would also depend on if you're married, have kids, and what your lifestyle is like. If you're used to living at your previous means, then taking a 40% pay cut would require a bit of a lifestyle change. Most people wouldn't choose to make such a change.I guess it also depends on your preference between working for someone and having your own startup. I think you can do a startup without killing yourself.Another thought: A 10 year old company probably isn't going to give you equity. But, with their first in-house coder, they might get the web-app/product bug. Maybe you can negotiate equity rights to any product/spin-off that results from your work.
