I'm a former airpac......(icepac) pilot.  It's a pretty good place to build some quality time before hitting a commuter.  Greg, the owner, has an open checkbook when it comes to maintenance.  A couple of the training guys are horizon pilots that come back and give checkrides for the extra dough$$.  Just don't do anything dumb, like hit a mountain, and you'll have a good time.  Seneca's are not the best in the ice but usually your just carrying styrofoam boxes with medical stuff so your not heavy.  The chieftan is a great all around airplane.  I think the beech 99 is parked but they may still have a couple C-404's hanging around.  The 404 is a cool airplane but you have to baby the engines.  After a winter there you'll be ready for anything.
Have fun and good luck
