For metal, l'd suggest the Nomad, a Bantam, or a Tormach mill (I don't know if any of these are in stock). You could also get a manual vertical mill and cnc it. Grizzly and Little Machine Shop are both good companies and have mills in stock. (I think Precision Matthews and Dropros are back ordered). Then, you can get anything you want for wood, since it's a lot less demanding. Source: about 3 years ago

The Nomad or the xsTECH Router are the first two that come to mind. Source: about 3 years ago
