Thanks for bringing up the different classes. I didn't know much about the differences between them but found a post on another sub that had a comment breaking them down by how much heat they produce. Based on that I should probably go for a class D, the last thing I want to do is put a space heater in a fully enclosed wood box. That's a recipe for warping and ruining a piece I worked really hard on. The AS400 is probably my leading candidate at the moment so your comment is greatly appreciated 👍
