What Carl in post #10 said. I've been building models for the last 50 years and have both a band saw and a scroll saw. The band saw is by far the best choice if you can only have one. Just get a 2 wheel with as big a throat as you can afford. For the few times you need inside cuts, use the hand powered coping saw. Stay away from those mini saws unless you are only doing very small models and only cut balsa.
