Best 3D Printer that uses Metals as Filament?

[Marcus]

The problem is the complexity of Laser Synthering printers, I am not aware of any (new) metal printers in that price range.
I'd recomend the lost-PLA-casting method for metal objects, or prototyping with plastic, later letting shapeways or another service print it in metal.

Good luck finding a printer!
Keep in mind that metal powder needs careful handling!

I'm not familar with the lost-PLA-casting method. What exactly does that mean? Do you print a cast in plastic and then use that with metal to make a metal object?
