try xplane
Xplane 11 is very cheap. Xplane 12 better still, under $100 as I recall. Can install on both mac and MS Windows platforms. Both 11 and 12 have a variety of aircraft with G1000 as well as G430, so there are plenty of opportunities to practice.
You will need a joystick. cheapest I could find was
Logitech extreme 3D (under $100)
