You can use:
- http://netrenderer.com/ to check all IE versions screenshoots
- http://cloudinternetexplorer.com/ to check IE live (IE9 only)
- https://browserling.com/ to check IE, Chrome, Firefox, Opera, Safari versions
- http://www.browserstack.com/ is commercial, but have a free trial
- http://crossbrowsertesting.com/ is commercial, but have a free trial too
- etc...
EDIT: I recommend, if you are using CSS3, to use http://css3pie.com/ is a super htc app, that make major CSS3 function to work in IE.
Hope this will help you!
