I dont know how many of you guys watch craigs list , If you dont , you should. I just picked up a 1998 100 cfm Ingersol rand tow behind compressor . For the whopping total of $ 600.00 . It has 1 fuel leak , and it needs paint , but runs real strong with only 1600 hours on it . That brings me upto 3 tow behinds , a 125 , a 90 , amd a 100 cfm , and a 30 cfm truck unit for a total of $ 3500.00 combined .
