Contact form

Hey all, iv been trying to find a good simple clean, lightweight contact form plugin that will let me add the Contact form into pages/posts.

I came here because iv been through about 4 differnet ones that came out top of the searches, and none seem to work!

Im new to wordpress, so thats why i havent created my own! and there seems to be thousands out there, can someone point me to a good contact form pluging please!
That works with 2.5.1 =]

Thanks
Tom
