Thanks for the acorn.
Yeah, that Bill Robinson one is not so cheap. But it is actually coming down every year a little bit (I keep track). So there is hope.
I was also thinking of the Pinewood ones like Pinewood Lilypad and all the spinoffs (Pinewood Green Flash etc), for the green one. They have the shape, but also have red edges.
They have this one that I had never heard of, sans red:

But not super-cheap.
you should click around their offerings (2023 also out now). They definitely seem to have shapes you may like.
