Stop by Fish Brothers sometime, they aren't far from M+M, great guys, mostly lumber, some ply, great folks.I do a fair bit of woodworking, and Dakota is my go-to for hardwood lumber. Haven’t gotten any plywood from them, but I stick with real 5’ x 5’ Baltic birch plywood from M&M Lumber for that purpose. Very pricey, but worth it compared to the usual cabinet-grade plywood that’s available. Especially if the boxes of drawers will be exposed when open.
BB has always been my goto for drawers, I don't use it for case work though.
