If you are looking for the highest quality cutting board I have found the source. Only problem is that this is a 2 board set. You might find someone to split the cost and then when you get the deliver you can split the product.

2-1/4" thick 24" x 30" hard rock maple cutting board.

Brace yourself. The set is over $200.

You could seriously beat a burglar to death with one of those suckers.

I bought a decent set off of craigslist for $20. It's a nice solid wood set.
