Avanti looks great, but is more difficult to land.
The aircraft has the range, speed, cabin and is reasonably priced.
Contact Piaggio for a demo flight, you'll enjoy!
(I friend did it and he is considering the P180 for a KA90 replacement).
By the way, I don't think you'll find a 2.5M$ CJ1. Priced at 3M$ more likely!
