I don't have a Marquis, I have a 1972 F model, the "low performance" MU2, only 260KTAS vs 300KTS. Burns less fuel though. Training was $6K initial and will be $3K annually. Insurance was $9K for $250K hull value. They required 50 hours dual, and that was about right for me. The MU2 is my first turbine so there was a pretty big learning curve. I wanted twin safety, and a turbine actually gives you that. It will actually climb on one engine, properly flown. One thing to keep in mind, both the MU2 and P337 have lousy safety records, but the MU2's has improved due to the training requirement. Something to keep in mind no matter what you fly. My 100/200 hour inspection was $12K plus a $3K battery that was welded to the battery connector. That is in the range I spent on P337 annuals, and less than my first P337 annual FWIW.
