3D Metal Printer purchase?

I am looking into a 3D metal printer.

A unit that i can print with a direct laser without support structure, I need brand names and models please. something medium sized, i only need it to print objects roughly 3x3x5 inches in size,but reasonably detailed at the 1/16" scale.

Also, can someone please give me some information on the 3D scanner i have seen in some commercials where you can scan objects and import that into a CAD program.

Thanks
