Although many (most?) people know about the Hot Plot, and even thought of it during the cute toy conversation, we probably left it out for cost reasons. Although it's on the low end of the RP machine spectrum, my memory tells me it's more expensive than a toy. What does a Sparx machine cost these days?

As for the JP System 5, or the Hasbro toy for that matter, wouldn't either one of those be more inteesting if we had an inexpensive laser scanner as an input device for them?
