Samson sells spider shock mounts. They look similar in apearance to Neumanns that sell for hundreds of dollars.
They cost me $29 apiece. The Sabra shock mounts look very cheesy to me. I own them and don't use them.
Sometimes I have to drill the Samsons out to fit certain Neumann models. The elastic on the Samson shockmounts lasts longer than Neumann elastic.
There ya go, one fifth the price of Neumann and more durable.
