Processors have many options to consider for improving production efficiency or expanding capacity besides investing in the latest and greatest machinery. Often there's no substitute for the technology in new equipment.

Meanwhile, bargains in used equipment abound. Unfortunate for some-but fortunate for others-are the plant closures resulting from a shifting manufacturing sector. The equipment liquidations that follow are where expanding companies can find good deals on used machinery.
