Multiple Internet Explorer instances on one machine [duplicate]

Running Internet Explorer 6, Internet Explorer 7, and Internet Explorer 8 on the same machine

I am looking for a tool that can allow me to run Internet Explorer 6, Internet Explorer 7 (and Internet Explorer 8 if possible) on my machine. I found something on the Internet like this and some other interesting solutions, but I need your opinion based on experience. Which is the best choice for running multiple Internet Explorer instances from the point of view of a web-developer?

Edit: thank you for the help, I installed some of the tools you suggested, and I decided to stick to those two: IETester and IE Collection - easy to install, intuitive UI and fast response time.

The others:

xenocode just crashed or I couldn't install it properly.
Multiple IE wanted me to install Microsoft .NET which took eternity and at the end, surprise...nothing worked. Then again it's probably my poor installing skills
IE Application Compatibility VPC Image seems to be the most professional approach to the issue but I just liked IETester and IE Collection better.

I've used this:

This will get IE 6 going and earlier versions if that's a priority. Then you can just install IE 8 because it allows you to use IE7 "compatibility mode" so you can effectively mimic IE7.

Microsoft provides VPC virtual hard drives with various OS images and IE versions for just this purpose:

Note that the OS installs are time-bombed so you have to periodically download new images from MS.

If you're on Windows you can try the new SuperPreview tool: http://download.microsoft.com/download/5/6/8/568F0D28-0434-4794-B7FC-FB293BCC98FB/SuperPreview_Trial_en.exe
