If all you have is simulator time, and you want to build a kit, then build a trainer.
The idea that your even thinking about building a SSE for your first kit--when you've never even flown a real plane is just rediculous IMO.
Build your trainer, then you can actually go out and fly instead of talking about flying.
There will be plenty of time for building SSE and warbirds later on down the road after you actually learn to fly.
