Bentlyj- I think I have avoided learning SU due to wanting to avoid more "computer time" in my hobby. I'm at my desk a lot for work related stuff and when it comes to my recreation (woodworking is that for me), I want to be in my little shop. I know I would be more productive, more efficient, etc. but my brain hasn't gotten my heart to give SU a try. Maybe it's time to see how it would impact my experience.
