One thing to think about, when using a simulator, is that IF you don't know what you need to work on, it's wasting time and money. Buy your simulator and leave it in the box for now. Spend a day or two at the field with an instructor and (if available) the club's trainer. The instructor will be able to tell you what to work on using the simulator after the session(s) and make your simulator time more effective in helping you learn to fly rather than just flying around and crashing on the screen
