Cost-Benefit analysis:
Ask your girlfriend how she'll react if the Nexstar doesn't survive the maiden flight. Read the manual that comes with the Nexstar, paying particular attention to the warranty that if it crashes while under instruction with a qualified AMA instructor, they'll replace it.

Now compare that to the cost of an instructor with a buddy box (AMA Dues, Club Dues), maybe having to wait a week or two longer to fly it.

Your call.
