Yeah, wineadors are great, basically big fancy tupperdors or coolerdors. Ages ago I converted a cheap $100 wine cooler into a humi. Took out the wine trays, bought some spanish cedar from a lumber store and just made my own shelves. Worked like a charm - the refrigeration should provide all the moisture you need, so some humidy beads like Heartfelt or whatever will keep the RH down; obviously a digital gauge so you know when to water the beads if the water from the cooling coils isn't enough. Just plug the drain hole in the bottom with some aquarium caulk (because it's food safe) and shove a few beads on every shelf.
Mine held something like 800-1,000 churchills, loved it, but had to leave it behind in a move, broke my heart.
