RE: Which simulator ?
I would consider your computers abilities in considering a new sim. You don't want one that can't run smoothly. I have used that when I gave a sim as a gift. If you have a tricked out gaming computer, then consider the support offered ( updates, new planes and scenary). I have trained people to fly on a sim, then put them into a .40 sized trainer with just a few flghts and very little knee knocking. I wish I would have had that as an option. Good Luck!
