I've been flying both 2's & 3's for over 10 years....currently flying a hushkitted 3 out of PBI. Hawkerjet's post is very good on operational considerations, with planning you can take these a/c almost anywhere. As far as maint., we plan on as much as a 1K/flt hour, and we're usually a little high. The problem with the 2 is initial cost vs resale value, most of them will be parted out, and the range requires more stops.
So, if a buyer is willing to probably write off the bird when it's time to buy something else, there's a lot of bang for the buck, I know of one G2 being offered at below 800k.
