Of the 3 types within your budget you mentioned in your latest post the Astra, although not sexy, is fastest and has the best range by far. West Coast-Hawaii most days of the year without wet footprint.(you haven't mentioned going to Hawaii but this example is often used as a good-range benchmark). I flew an Astra for 13 years in the 80s and 90s and learned to like quite a lot about it. We would make regular trips from US West Coast to London with 1 stop. 2 stops coming home. Good runway perf too. Downside is the narrow cabin but it does have stand up cabin if you are 6' tall or less. Full lav and external baggage door too. Early builds (non SPx) are available for a bit over $1M. I saw SN 018 (?) for sale the other day for $495K. Must have a story...Maybe avoid that one. It's been a long time for me and I don't know if Gulfstream even supports these old birds any more. They pretty well ditched the whole program once they purchased Galaxy Aerospace.
