Renegade's Robo Rally Worth It?

Has anyone bought the new editions made by Renegade of Robo Rally or any of the other rereleases?

I'm curious how the component quality and overall build quality is. I have the WizKids that is the previous version of the rules, so I don't really need it. That said, I'm curious about the new rules and the fact Renegade has already produced two expansions makes me even more curious.
