I fly an SII for a while and I hated it.
Didn`t heat in winter, didn`cool in Summer. The TKS very often had a light showing, despite us using it on every flight to keep the holes and lights going...
Pax didn`t like it too much either. Good troop transport, but....
And mx ain`t cheap on them either. 150 hrs intervals and a phase V every 3 (?) years with 3-4 weeks down.
Don`t know where you want to operate, but make sure the avionics (CVR, DFDR, RVSM, TCAS, EPGWS, 8,33 etcetc) are up to the task in the area of intended use. Otherwise you could end up spending - easily - the worth ot the airplane in avionics upgrades...
