Idon't believe mode matters so much. It depends what you learn(ed) on. I have heard that Mode 1 has an advantage for left-handed pilots.

If you are going to have the opportunity for a Buddy-box then it may matter to your instructor.

I would recommend a flight-simulator. Helps with "cheap" mistakes while picking up the techniques.

I would also recommend a varl light, small, profile - possibly even indoor - 3D model. Something you can use in a small area.
