Permafrost burial has been explored, but is generally considered an inferior option. If I were going for a cheap cryonics substitute, I’d try plasticization. A lab can do a head for a couple thousand bucks, it preserves enough microstructure for an electron scanning microscope, and there’s no worries about staying cool.
