Monitors are falling

I am soliciting advice ... opinions even ... on what to do with my rig. My stand mounted B&W CDM-1SEs were almost the victim of a knock down over the weekend ... by my wife of all people. This started the 'this is a living room not a media room' diatribe. Insult to injury is the fact that our first child is on the way. I beg you for suggestions ... ideas tto make the CDMs more stable or a really nice floor stander that I can get into in the $1,000 - $1,500 used range. All opinions are welcome and appreciated.
