I need some sound effect's.

I have been very busy for some pass few day's making a promotional video for marketforums. This is what I got so far but I'll try to remake it and make it more HD.

I might make it much more different. (This is not the full clip just a sample)

I know some good sites, I searched for hours on the web when I needed some sounds.
Can't remember them right now. But I'll look it up tomorrow (almost midnight here).

OK have you found any, I really need some for the video.
