Wanted: Sluice Box

[Red Doe]

I was at the Monroe Gold Show and there was a sluice box for sale there. It was smaller and plastic. Gray in color. They were asking $49.00 for it.
What I was wondering is.....does anyone know who was selling them??? I was not able to get one there and was gonna wait until the GPAA show in Puyallup, WA...but they were not selling them at the GPAA show. I have tried looking on line with no success.
Thanks....
