I have both the Oneway and Spin Doctor steady rests.
Both are quality, and work well.
The Oneway is something I couldn't live without. It works, and definitely does reduce vibration. It would be incorrect to state it will aways eliminate vibration. There are times when it does, sure......but a reduction in vibration is something that is very helpful, as well.
The Clark "Spin Doctor" steady rest is also a good one. I special ordered a 5-point Spin Doctor, and I've completed a few bowls that were impossible for the Oneway to handle.
Generally, the really big and deep bowls are those that best benefit with the Clark steady rest. For 90 percent of the turnings, the Oneway does fine, but those few times where the Clark Spin Doctor works better, is priceless!
For anyone contemplating a steady rest, I'd suggest getting the Oneway first. It works, and for most applications, works well. Not everyone will need the Clark rest, but a few will need something that big........In my opinion, everyone will benefit from the smaller Oneway bowl steady.
The Clark rest is very heavy, as was stated. That something you can live with, given the great benefits it yields. For those who have physical limitations that hinder mounting this rest to their lathe, may I suggest a simple pulley and rope attached to the ceiling?
