If you're in Western Mass you might consider taking a short drive to Conway Hardwoods in Gaylordsville, CT. That's on Route 7, north of Danbury. I discovered it this past summer only months before I moved to Maine. Most of their business is custom milling wood for hardwood floors. They had quite a nice selection of mahogany. I got somwe cherry for the gunwales of my Wee Lassie.
