I like this one...a beam engine and pumps water...$299 at ministeam, did they ever offer this model as a "kit"?

Nope...

As far as i know, the only Solar engines offered as a kit while Pm Research has owned the brand, would be the Solar #13 "Thinking Man´s Engine Kit", and the Solar#15 "The Glassworks Unmachined Kit".

As far as the Solar #12 Rider Ericsson goes, both John and Bruce has made some very nice modding efforts to slow these down, to a way more realistic speed:
