I've never owned a sim.. I did try some free one's...
And I think it can help in some aspects of flying..
As I've been told there are some newer ones out that give
you more control and additional aricraft.. There not cheap..
But if it helps you in gaining some needed help with the plane
that your now flying or one that you will get in the future.. I
would say go for it.. It's a LOT better/cheaper clicking on the
reset button, Then to have to fix or repair the model...
