Ya I bought that one from Vintage Blades LLC. It is made by Col. Conk. Pretty nice stand. Yes the base is heavy enough to support a Vision on one side without a brush counterweighting it.
I've got the same stand and use it to hold a Fatboy and small Vulfix brush with no problem. The base is pretty darn sturdy in my opinion. I hang my brush by the base instead of by the collar next to the bristles, not sure if that's what is recommended but it works fine for my brush.
Have the same stand from Em's Place. She'll sell you an additional fork for oversized brushes that you can insert under the screw-on knurl.
I leave it on the sink. This one stand allows me to store any wet brush inverted for 24 hours before storing upright in the cabinet. Additionally, I can leave the razor dry for the same length of time.
