I want to get a simulator that is free (or cheap - under $20 hopefully?)

I have FMS, and can fly the gliders well, but when I took my powered glider out, at minimum control speed it was hard to use. I tried the demo of another simulator, and was hopeless. So, I want a simulator that is harder then FMS, has a powered glider (or something like that), and mayby (it would be useful) give you more useful info about crashes - eg what damage has been done. For me, the price is most important.

Any ideas? - Andrew
