Have you tried inkscape (http://www.inkscape.org )? Provides pretty good vector graphic editing facilities a la Corel.

I haven't looked closely at the latest release yet but my impression is that it has some way to go before it matches the later Coreldraws. And I have been creating graphics that really push it to its limits. So I am loath to move to something that is less featured. Doctrinal purity has its limits.
