That does look like a useful cooker! Never seen one of those and it looks great for Scamp
I have a small toaster oven installed under the kitchen top cabinet. I don't like microwave
cooking, save for a few items that aren't made mushy and rubbery by the devices.
But the toaster oven is prone to making smoke/burned smells if you are not very careful how you cook and keep it clean. And if I put it on high and just left it a few hours, it might just set my trailer on fire! Seriously, I don't think it's a huge issue, but would never leave it on unattended, the cabinet over the toaster does get hot if you cook on high for more than 5-10 minutes. So no long baking at high temps!
