Hi! I'm needing to buy a used trailer-mounted diesel air compressor for a new business and haven't been able to find a source in DR. These are the units you typically see at road construction projects operating jackhammers or other air-driven equipment. Need a 210 cfm or larger and hate to even think about buying new due to price. Any suggestions on where one might be available on the island? Living in Santiago but any location is fine. Thanks, Ed
