And how far can you fly in an EMS configured 145?? A lot less than an EMS configured 169. Heck, a 145T2 won't even go as far as a BK117B2!
Oh, and I believe the 169 is the same price, if not cheaper. Same delays with FAA with the 169 as there were with the 189. Reciprocal agreements aren't so reciprocal when it comes to Type Certs with new avionic packages. For the 189 they eventually went with a VFR cert for FAA because FAA was so slow approving the IFR package!
Don't blame the aircraft for regulatory slowness.
