Personally, I like the feel of solid wood. Don't bother with these tiny boards that everyone seems to have in their kitchens. They are not user friendly. Nothing could be further from the truth. It is as essential as a kitchen stove and should be in everyone's kitchen.
Nothing works better for mixing a multitude of different preparations or for making sauces or gravy.
Buy a solid stainless steel whip with moderately stiff wires. Very thin wires are for mixing delicate things like egg whites or whipped cream. Very thick, solid wires are for mixing stiff dough. With use, spot welded ladles tend to come apart. Buy several different sizes.
