It sort of depends on how you define "consumer friendly prices". AFAIK, in the $1000 - "slightly over or under $1000" range, 24GB is all you can get. But there are Radeon Pro boards with 32GB or 48GB of RAM for various prices between around $2000 to about $3500. So not "cheap" but possibly within reach for a serious hobbyist who doesn't mind spending a little bit more.
