Guys, I have found this machine for sale but the guy doesn't know what he wants for it. I believe it is a Jacobs 26 but dont know the difference between the the various models. He "believes" everything is there but unsure. What would be an "average price" for the machine in this condition. He also "believes" the compressor works... or at least that is what he was told. I know these are rare but can be found. Thanks! Jeff
