All of us wished we had someone to cut our machines for free... So if you have the resource use it. Start with the gantry, motor mounts and bearing areas. And expand to all that you can get in. Depending on the size table they have a 4 x 8 sheet will yeild a lot of parts. After you have sent them to work on that... I suppose you are in a hurry for the build (most of us are) and have the budget, Buy a plug and play setup. There are many listed on the Zone and depending on the size table are really affordable. As opposed to hunting ebay and piecing the thing together and hoping you get a product that will run. even then someone here has done that and can help.
