I have one of those measuring trays, bought in Japan at one of the dry goods stores 3 years ago. The price then was either 9000 or 18,000 yen. Sorry, memory is bad about that. It was also expensive to ship, as it didnt fit into any regular koi boxes because of it's length. Essentially cost the same as a box of koi from Japan to ship it, and luckily I was able to split the cost with another hobbyist who also bought one. Mine was shipped home through Infiltration.
So I have one, but have very infrequently used it. It is much easier to use the square tub I marked years ago.
Hope that helps.
