Vice for workbench

I'm working toward building a workbench and I want to get a good vice for it. I currently have a small vice in my old bench and it has a number of annoyances. It's quite stiff to turn the handle, the jaws don't open nearly wide enough, and it doesn't have a quick release.

I was looking for something like this:

any suggestions as to what I should get, and where from in Australia? and what size for that matter?

Thanks
