Home Care Software

I am looking for a software that I can download from online that could allow me to edit my videos. I am looking for something with good editing tools, but ideally nothing too confusing. I am very impressed what I see in imovie ‘09, but I do not have a Mac, nor do I care to pay 80 bucks for a package deal. Something cheaper would be preferred, and something that works with Windows Vista Home Premium. I would like to be able to cut video footage, add stills and play with sound. Any suggestions?
