would agree
that a Hawker 4000 is just the same as throwing money down the drain..
Falcon 50 EX ist an excellent aircraft, you probably can get a good one for around 5 - 7 Mio USD...smaller cabin though and only 3200 NM max
Older F900EX, excellent as well and within price range...
If you do not need the cabin of a F900 series.....THEN...
well I would look at nice F2000EX EASy, preferably fresh out of a C-Check or with a C Check included...install the winglets, get the SB for the higher MTOW..
et voila...you will have a "new" F2000LX...
the absolutley best and most reliable bird in that class...for all practical purposes the same range as a F900EX...
the cockpit will be easily upgradable to the newest regs envisioned with EASy II
dream to fly...no problems whatsoever...the folks in the cabin love it, because of the comfort and probably the quietest cabin in production today..
may defintely be in your price range...plus the lowest DOCs in that class
as the old saying goes...if you need constant 3000 - 3300NM range in all directions plus reserves for all kinds of weather you need a 3800 to 4000 NM bird anyway...
