Featured Post Slider?

Hi, I am looking for a featured post slider that actually works.

• I need to be able to set the dimensions (around 550px wide)
• I need it to have control buttons (pause, next)
• I need to choose the posts (not just the latest)
• It needs to be simple to install. So many talk about jquery but i don’t understand what any of it means.
• It needs to be free and without watermarks

Don’t suggest Featured Content Gallery unless you can tell me how to make it work because that is what is on my site now and it’s just listing posts. I’ve already tried deactivating my other plugins. I have the latest version of wordpress and the default theme (kinda-i just changed widths, images, colors, and such). I’m tired of that and now just wants something I can upload to my plugins folder and it works automatically.

Thank you!
