Chemical fixation (sometimes called “plastination”, although this conflates the practice with an unrelated procedure) is an in-progress technology to preserve brains at room temperature, and is being evaluated alongside cryonics by the Brain Preservation Foundation: http://www.brainpreservation.org/
It would probably be cheaper than cryonics, and would require much less long-term support—you can throw the brain in a shoebox instead of constantly maintaining it in liquid nitrogen. It still lacks a revival mechanism though—the current hope seems to be preserving enough information to get it back via slicing and scanning later.
