The best all around material that can cost anything is a contradictory sentence //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
The best all around material for building would be MDF, 3/4". It's strong, dense, cuts easily, and is the best value for the amount you get.
The best around overall would have to be baltic birch, 13 ply though. If you're in a store and it looks expensive, then it probably isn't baltic birch. You have to go to a high quality lumberyard or cabinetry business, and is usually around 60-80 per sheet (not 4x8 either). It cuts like a chainsaw through butter, holds like grandma and looks beautiful when finished.
