I would get a 350B2 with 2 Squirrel cheeks. It adds a lot of room to the side baggage compartments. The B3 is very nice but I think he does not need one.
Get a brand new B2 with VEMD (glass) cockpit. With the money saved B2 vs. B3 a nice avionics/GPS package could be installed.
Oh,and get the all glass doors to get the most visibility out your A/C.
