Citation VII pro and cons

[oceanpilot]

Anybody out there flying or operating a Citation VII C650 ?
We are looking for a stand-up cabin with range 2000NM + sure.
We operate Citation already and adding an EXCEL would be nice but no range
and Sovereign is new (reads expensive purchase)

A III VI VII is the next choice only not a lot out there. The investment is fairly low
Total built only around 200 but this maybe has to have a reason.

Any advice about the VII appreciated; operation costs, flying it, special problems (if any) .

Or other recommendations / comparisons. Hawker 800, Lear 60 (before somebody comes up with something exotic we are operating in SE Asia.)

Thanks a lot.
