Wesley,
The board that I have is :
1. Well made.
2. Has given me great service for several years.
3. Hardly shows any signs of wear from being used.
4. Is not falling apart like some of the less expensive boards I've had.
5. It is a large work surface (432sq/in.)
6. It's heavy so it doesn't move around when being used.
7. And I Like It!
I feel like it is great piece of equipment! (Of course, that is my opinion.) So, I guess what makes it worthy of it's price is MY satisfaction with the board. I shopped around for a while before finally purchasing the board. Williams-Sonoma is a pricey place to shop, but I ended up in their store in Charlotte, NC. I found this board, and determined that it was exactly the board I had been looking for. I had not found a similar board at ANY price. I think it was only around $70, eight or nine years ago.
I use smaller, cheaper boards for light duty stuff. I even use a plastic board quite often. They are useful for some jobs, not for others.
