RE: Flight sim on a budget
-Realflight Basic is under 100, but is limited in what you can add to it. (nothing)
-Ikarus has several inexpensive versions of their simulator, such as Easy Fly, but I have no experience with it. It looks pretty good, though.
-You should also be able to find a copy of FS One for a good price. It is pretty good
-Personally, I'd try to find a copy of Phoenix as cheaply as possible. It is really fantastic, better than Realflight in my opinion.
Hope this helps!
