If you don't mind putting up with seeing an IE window opening up for buying the full retail version after each burn of an iso image I've been working with the free version of BurnOn for some time now. That includes varying distros downloaded in iso disk images as well as the Linux drive tool GParted.

With a good brand of blank cd-rs you can get reliable burns with the free version. Eventually I will get the full retail version here since I am always running into a new distro or newer version of GParted to try out. In fact ubuntu 7.10 is presently the default OS here that then loads the dual boot loader for Vista/XP.
