Mesquiteman - thanks very much for the suggestion. I actually have thought about it; the company I purchased from - Ozarkwest, makes mesquite boards too. Mesquite does sound great aesthetically too - I love the reddish, warm look of aged cherry, and I understand mesquite has a similar look.
I talked quite a bit with the owners of Ozarkwest who make the cutting boards I liked. They make almost every wood combination imaginable; end grain boards using either one single wood, or two different woods with a contrasting border. I had a really hard time deciding, but in the end I figured I should trust their opinion and advice since they've seen all these different boards in person. They told me their favorite is the all-walnut board, because it has the richest and most interesting grain and appearance. And, because the dark color is unique, rich and looks great with the contrast when cutting brightly colored vegetables on it. I should receive it in the mail in the next few days. That mesquite photo you posted really is beautiful though - do you make those boards? If so, how much are they? Thanks again.
