I have two 12-bottle units by Edgestar, one for red and one for white. They use thermoelectric cooling units that have no vibration. They have small internal fans to keep the temperature evenly distributed which don't cause any appreciable vibration that I can notice. I have internal temp/humidity gauges and it looks like the temp stays within about a degree. They aren't humidity controlled, but I put a cup of water in each unit and the humidity stays about 65%, compared with 28% in my house. They also have tinted glass doors, LED internal lights and available teak wood shelves. The units come in 18 and 24 bottle units also. So far, so good for a fairly cheap introductory unit, short term storage.
