I feel there is no substitute for an instructor. I'm not sure if the sim even shortens the leaning curve, it may just be the person learning. Some pick it up very quickly while others never seem to get it. I personally can't get myself to buy a sim for $200, I would rather spend that kind of money on a couple of good kits and enjoy them for years to come. A sim would be nice to have during the times when weather just doesn't permit flying, but that's when kits seem to keep me occupied.
