If you can find a Beech 1900D that is not older than 15 years in good condition, I would go for that since you are planning to fly tourists - then you will not run into payload problems in terms of luggage and will give you more flexibility. The operating costs are only marginally higher, than operating a B200. Another option if you want to trade the space for a little more speed, is the B350 - and those are still being produced - brand new.
