I am bringing this back, as I have a similar question...For travel delays, etc., I relay on credit card insurance coverage.

For medical I have been using the Trekker Choice from GeoBlue that was recommended by Stefan, which works well with BlueCross BlueShield, my home insurance. It has global coverage and pretty affordable at $175/year. However, upon closer inspection I saw that the annual medical coverage limit is $250k and $500k for evacuation. Dental coverage is only $100-200/trip. These seem a bit low to me, although certainly fine for the premium paid. What do you guys think?

It also doesn't cover injury from terrorism in countries where there are US travel warnings, which is a lot of countries, like Egypt, hmm, hello, this is where you might need it, right?
