Testing with IE6, IE7 and IE8 on same machine {without using VMware/VirtualPC images}

Hi All,
  Previously i were able to work with IE6 and IE7 on the same machine with Multiple IE installer with the very satisfactory result.
But As IE8 is released and MultipleIE installer no longer maintained by tredsoft I don't know which will be the most easiest way {while not using VMware / VirtualPC images} to test my Application on These 3 browsers.I have heard about Final Builds Site - Internet Explorer Collection in a comment in http://tredosoft.com/Multiple_IE?page=6
Please Suggest me the most convenient way
