What’s your budget? Do you need 3 axis or do you need a rotary 4th axis addition? What about automatic tool changer? What CAM software do you plan to use? I have a little bit of experience with some Roland mills and VHF mills for dental/jewelry. I know you can get a Roland MDX540 for pretty cheap these days and it will do the material you listed. The Rolands are build a little cheaper though so they aren’t the most solid machines.
