Like Keith, I use the On-Stage Flip-It A-Frame.
The hinged guard that keeps the neck in the cradle is a big improvement over the basic A-Frame stand as it significantly cuts down on potential disasters.
My bass is always on the stand rather than in the case, since I'm always around the house and I often pick up the bass to practice even if it's only for a few minutes.
I always remove the instrument cable from the jack before I take the bass from my shoulder. And I always remove the strap before setting the bass in the stand.
My house is not air conditioned, and my neck is always responding to the changes in humidity. Given that, I don't want to hang my bass from the headstock.
The On-Stage stand is not well built; but you get what you pay for. The hinge is not incredibly well built; it's hanging by a single pop rivet. I have three, and none have failed. But the build quality doesn't inspire confidence.
But given the other available choices that I am aware of, I wouldn't use anything else.
