Also, you asked about the difference between buying from Gandy and buying a full USA body. Well, the passport warranty is one. Instead of the 1 year that Gandy probably offers (perhaps it is more...I have not checked), you get 3-5 years. For those 3-5 years, ANYTHING that goes wrong with the camera will be fixed for free as long as you did not do it on purpose. Let's say you are running across the street and drop your MP and an 18 wheeler runs over it. As long as the serial number is readable, they will replace the camera at no cost to you. This is very unlikely to happen, but it is a nice thing to have. I have had two problems with my very early MP -- the eyepiece needed to be sealed, and another time the shutter curtains had a light leak problem. Both times I sent it back, it was repaired and sent back to me within a month. The second time (I was understandably upset), they did a complete CLA. These are complicated cameras and repairs are expensive, so it is not a bad idea to have a good warranty. For lenses, I would, and do, often buy grey market because they don't tend to have as many problems. In any case, that is just my two cents.
By the way, I bought my MP from Adorama right after they came out...2250 dollars...ah, the good old days.
