RANT
RAnt is more of a technical teaching tool to improve someones understanding of how all of the navaids work and how you are positioned in relation to them to give you the picture. Situational awareness stuff more than anything else.
For good hands on stuff, Microsoft Pro 2004 is good. Even better with a stick and pedals.
X-plane is good as well but the real key question is budget and cost.
It may be worth waiting to see what the new MS FS is like.
