As someone who has an order for 20+ on the books, I suggest you stay the hell away. We don't need any more airlines ordering F100's and clogging up the production lines.
But seriously, it's a good plane. The Boeing 717 is a good alternative if you can wait for it and don't want to try and beat the crowds ordering the F100. There really is no secrets on how to use it--it's range is ~1500nm and like any other plane, the shorter the route the better. The F100 basically replaces the BAC 1-11 as the 100 seater of choice and you'll find more than a few airlines anchoring their fleets with the BAC 1-11. You should be able to make the F100 (or B717) the workhorse of your fleet and be wildly successful.
