It's very close to not being worth it for me. What's worth being away from your family, friends, and home for half your life. Remeber that you aren't gone 1 or 2 days. If you have a good line at a good airline (not great but good) you're probably getting 15 days off. That means that you're in a different city for half of your marriage, half of your kid's life, half of -your- life.
At what dollar value does that start to be attractive to you? Think hard about that.
