As with all aircraft acquisitions..........First define your requirement.
"I want a jet" is NOT a requirement
Max/average passengers, one or two crew, max/average distance, number of trips per/week/month/year, local airfield facilities (length of runways etc), local maintenance availability/expertise........
You already have a max buying budget. What about a running budget?
How about considering a few minutes more in the back of a KingAir for saving a bucketload of dollars? And maybe getting much more range?
Maybe fractional ownership is the best way to go?
