For a PC, RANT is very good as an instrument procedures trainer. Otherwise, more upmarket and more expensive is Elite. Also available are apps for your tablet. I have one just devoted to VOR tracking for not much money, which I use for showing the basics, definitely good value for money. Visit your favourite app store for details.
Whichever you choose, you need to have an instructor with you to show you what to do. That's more important than the choice of sim package.
We have an aged Frasca 142 sim which is no longer certified but those doing IR(R) or IMC courses find it very useful (and a fraction of the cost). It simulates vacuum instruments rather than a modern 'glass' EFIS but then so do the majority of training aircraft today.
