Looing for another machine for short run production.

[Mandingo]

We have a Haas Vf2 for our die making and the short run production is taking time out of producing the dies (only have 1 cnc). We need to purchase another vertical mill for the short run machining production. We don't want to buy a brand new machine and drop 40-80 k on it for piddley stuff. Anyone have any suggestions on a machine or maybe a used machinery company that is reliable? All the work we do is fairly small (under 12" long) so we dont need a large machine.
