I've been roasting coffee (typically no darker than FC+) on a West Bend Air Crazy popper since January. While I currently live in Virginia, I'll be moving to Nigeria for a two year assignment starting in December. I assume I could use the air popper on a transformer (220v stepped down to 110v) but that it would greatly increase stress on the fan motor due to the 50hz frequency in Nigeria. What would be your suggestions for a reliable and effective roaster that can make the journey to Nigeria, as well as future moves to other international locations? Are dual voltage roasters a thing? I'd like to stay south of 400 dollars.

Many thanks for the help!
