I am currently unable to be out in my shop, so rather than being out doing my own machine work, I am considering buying a machined engine kit. I know many here have bought such kits, and would appreciate some input on which ones should be considered.
I need one that requires NO machine work, although some minor hand-filing, sanding, and drilling would be possible. It could be a steam engine, Stirling engine, or even a hit and miss engine, but many might be ruled out by my desire to keep the price under $500s US or 400 euros, if that is realistic!
