Just $28 in pine, from Menards. The two shelves are panels sold at Menards. The legs are resawn from a 2×4. The spindles were resawn for a 1×4. The aprons were re-sized from more 1x4s, and cut down to 3" wide. This will get a paint & contact paper finish, so why use "good" wood? More pictures..
A view of the back of the island. Bottom shelf was cut to fit. If needed, a second shelf can be added, later on. A few cleats and install another shelf. Not bad for just some pine and screws.
