And if you ever want to see NK yourself from the inside, check out http://www.koryogroup.com - took a tour with them a couple years ago and was an interesting experience.
Once you get to Beijing ($600-1400 from SFO), a 3-6 day trip costs $1-3k depending on EUR/USD, exact itinerary, and when in the year you go (winter trips are cheap). I know a few people who have gone and loved it, although I'd prefer an Antarctic cruise.
