Either that, or have the cordless drill on hand ;D
Seriously though, I believe (although I dont have any personal experience - I jumped straight into a corretto) the basic issue with a standard popper is that it is really efficient at browning the outside of the beans quickly (3-4 mins) but doesnt leave time for sufficient roast depth for best flavour. A lower powered popper will take slightly longer, and should help a bit, but when an ideal roast time is 15-17 minutes - I dont think any popper will do this out of the box (please feel free anyone to jump in on this anyone!).
So I think any machine you buy can work well - but youll need to be prepared for some basic tinkering whatever you get, even if its just a chimney extension…
Lots of threads on these mods on the site - so just go for it, and have fun!
