So far I have used three different toaster ovens. One I bought at a 2nd hand store for $12. It was so nice I decided to not use it for powder coating and donated it to my Church. The other two I found in the trash. Little bit of work and they work fine. I have a long thermometer that was with a turkey fryer. I drill holes in the toaster ovens to insert the long thermometer. That way I don't have to rely on the temp selector on the oven.
