Hmmm thought i'd seen this before. They do the exact same thing, but in MDF. The acryllic would be more durable and easier to clean spilt paint from though... and its the same price.
Years ago I found these guys but they didn't deliver to the UK then, so I didn't take an interest!! Now they do deliver to the UK I might put some funds aside and sort out my painting/work area once and for all!!
Thanks for finding and sharing dude!!
