This is really great, but I am much more interested in being able to test older (9/10) versions of IE as well.

Microsoft provides free VM images for IE6 through 11 -- https://www.modern.ie/en-us/virtualization-tools#downloads

Yea I am fairly confident in my site working in IE11 if it works in Chrome & Firefox, not so much in 8 and 9.
