I use that too lol. I have a strong gaming computer but it doesn't work too well.^^^ This
I've personally been using Powerdirector 11 ($90) and love it.
Movie Studio is like a watered down version of Vegas Pro. But should still meet your needs.
I used an older version of Adobe Premiere Elements which I had frustrations with earlier versions and it seems a bit over priced compared to either of the two above.
If money is no problem then Vegas Pro or Adobe Premiere Pro.
Still I would use trials to see what you are comfortable with.
