I'm interested in equipping my garage shop for some Kydex work. I doubt seriously this will ever be more than a hobby endeavor, but I would like to achieve professional-quality results and prefer to by quality tools that I can grow into rather than buying cheap and buying twice. If I purchase a toaster oven, are there certain features that would be worth paying a few dollars more for? e.g., is there a minimum internal size that would be useful? Any feedback would be sincerely appreciated.
