A friend of mine has two Macs, still in the box. He paid 75.00 for the 2.0 ci Mac 110 w/ 10" bar in 83 and wants 75.00 for it now. He also has a 140 with a 14" bar, that he paid 170.00 the same year. Are these saws worth 75.00 and 170.00? I've searched many threads here and have gotten very mixed reviews. The 110 has not been assembled yet and the 140 is in a plastic case packed in the box. Niether, never fired.
