I too had an issue. I ended up purchasing some 1 3/4" laminated maple work bench material from Grizzly Industrial and cut my own.
Isolation Platform from Timber Nation
If you need some maple isolation platforms or a equipment rack check out Timber Nation. Chris Futrick has made me a few platforms now.
Im just waiting on my custom brass rods to be machined, and will have a stackable rack.
