WTB: Dome diffusers for Z240s

Interested in buying a couple dome diffusers for Z240s. Located in Prince Edward Island, Canada.

Have a go at making your own - very easy - it worked for me:

So what was the photographic result?

My testing with the domes on land showed a slightly larger exposure field and softer roll off at the edges, compared to the flat diffusers.
