We are currently an all Ricoh shop and our 901+ Pro is tired after 4 years so went shopping. We looked at Ricoh, KM and Canon. I thought we would wind up with a KM machine, but was surprised when we finished our shopping and testing process by purchasing Canon. Yeah -- this is the first post in this thread to mention Canon. The machine appears to be better built, the quality is comparable, and the pricing and cost per copy were very competitive. Productivity on heavy stocks and two sided print appears better as well.
For years it hasn't seemed like Canon was much of a player in print-for-pay, except for the Oce Black & White boxes, but we feel pretty good about these machines.
KM talks about their registration system with the "visual" registration, but the demos sure showed white where there shouldn't have been. Maybe just because I'm an offset guy, but sure don't mind the gripper and guide method of registration.
Of course, it helps that we are in Chicagoland and about 15 minutes drive from major support facilities for both Canon and KM. I think service can be more important than the machines nowadays. If Ricoh was able to better maintain the machines we have we wouldn't have even needed to go shopping.
