Anyone with IE7 Beta want to help me?

I am making my first tableless CSS page and have just started styling the page.
I have found a great workaround to display transparent png files in Internet Explorer 5.5 + 6. (http://koivi.com/ie-png-transparency/)

Now as IE7 will support transparent .png files, I would like someone to test this site for me in IE7 to check if this method doesn’t go pear shaped when IE7 is released to the public.

Could someone check if the “best internet rate guaranteed” png under the check availability boxes displays properly in IE7?

[edit]Link removed, will post in site check when finished[/edit]

Thanks!
