How About the Little Ones?
For some reason, I've always had a fondness for the smallest airliners, the 19 seat planes. Viking Air has put the Twin Otter back in production, so that's the only one I know of being built now. PAD has a pretty good Twin Otter, floats and wheels.
The dominant 19 seater today seems to be the Beech 1900D, and PAD has a very good one. I enjoy flying that one. I also fly Rick Piper's HS748, a plane used in the Canadian Arctic because of its flexible freight/pax configuration. Of course, there's Milton's DHC7 which can shoehorn into any runway. Both of those planes are high quality models.
The DHC Dash 8 by PAD is good, and the Q400 version has a full cabin, but watch that you don't scrape the tail on rotation! POSKY's CRJs are great, and the EMB 195 by PAD is a more modern version of the regional jet. I just like the looks of it.
When I want to go really small, I fly the payware FSD Piper Navajo. Air taxi, charter...the aircraft is top notch and worth the money.
