A comparable new IR compressor could not be bought for less than $1, 000. There are a lot of oilless IR's out there for consumer use for much cheaper. Back then there really weren't consumer compressors -industrial quality is what you got. I've designed ptotection for compressors costing over $100k and the difference between consumer level, commercial level, industrial level, and refinery or energy level compressors is huge.
