I believe I'd been told that Rumblers were now out of production, but the guy who originated them was making another version of them by a different name that is just as good. Is this accurate, or did I dream that conversation? If there is a replacement what is it, and how can I get one?

I'd hate to have to buy another topraider to use for a week that will get thrown into the rolling topraider bin after the internal weights come loose and the thing quits running right.
