need help for facebook share buttons!

hello friends i need a little help for facebook share button how to add a facebook share button which can share current page of my blog not only homepage.
currently i am using sharethis wordpress plugin but it have a problem this plugin converts share url in a short link which might not good for seo
i tried a lots of javascript but they are not working do anyone know any javascript or a plugin which appears right or left corner of blog not upper or down section of post.
sorry for my poor english!!

i might be wrong but try shareaholics.You can set it so its at the bottom of each post.when you do a new post just click it and you can share it to your own page or a facebook page you manage.also lets anyone else on your blog share it too there facebook too

don't you have any script?
