I want to buy one for my own use, why would I be a shill for multiple vendors? I'm just showing some examples of the kind of stuff I've been seeing. The price is right but I don't want to buy a piece of crap, and I don't know what to watch out for.
If it helps, my use case involves some larger holes with higher torque / lower speed, so I'm less worried about, say, vibrations than breaking the stand due to high torque. The drill I have has a collar for a side handle and that seems to be the natural place to secure it on one of these things.
