There has been alot of good advice, but you can also go after Minolta and Konica corporate stability!! They;ve just merged into one company. Therefore, the vendor and or product might go through siginifgant changes passing head aches along to their clients!!
Also with 1200 D.P.I Resolution, 2 Scan 1 Pass Doc Feeder, speed advantages, software applications pertaining to their individual needs and DEMO with JOB Programs set up for their specific needs. the 60 will sell itself..
Good Luck
