You don't need a big budget to own an engine that really runs. Under $100 you'll find desk-sized Stirling engines that spin on the heat of a cup of coffee or an alcohol lamp, an easy first step or a gift that's simple to choose.

This range is also where most spare parts and tools live, so if you already own a TOYAN, SEMTO or RETROL engine, it's the place to pick up a starter kit, an ignition set or the right screwdriver.
