If you want high quality shockmounts at a low price, the Rycote InVision series are definitely the best. To be honest, the technology is so good it out-performs any shockmount whatever the price - that's why I am changing all my shockmounts over to this series.
They are also working on shockmounts for LDCs and I will get one for my Neumann as soon as it is available.
I know the designer, and have discussed the technology with him in detail - this is what I am buying.
