Pretty much a C404 with PT6s instead of GTSIO-520s. So lots of room and reliable engines with rather longer TBO compared to the pistion Gitsos. Usual turbine exposure to unexpected high cost if an engine finds a novel way to make smoke. Not that a cooked geared Continental is cheap either. Not pressurised so you can't take much advantage of reduced fuel consumption at high(er) altitudes. Unless everyone uses supplemental O2, or course. Still, Caravans, Skyvans and their unpressurised ilk get by just fine.
