You're right... I didn't notice that at first glance. Here's a smaller 4x6 sheet for $8.76 with Amazon Prime shipping: https://www.amazon.com/Magnetics-Gre...21-spons&psc=1

Silicone insulating washers/pads(for transistors etc.) costs next to nothing, mica ones are pricey - but still cheap compared to beryllium oxide ones(that is if you can get them - cause they are "big no no" in commie infested places...).
