@Meny, I cannot figure out why you always seem to have a bad opinion of a product while completely un-supported by any facts at all.
Why don't we try to help a guy out with some facts or at least opinions based on some type of fact.
@ original post, I would imagine since you are looking at the Komori G40, you are looking at new equipment so likely looking at the Ra 105 that I would call the "mid series". It would be based on the P40 machine that came out near 2004.
Both machines will do a great job on paper stock, both machines will run fast, though the rapida will have a slightly higher rated top speed. Both will MR quickly with the KBA having better fully auto plate changers. Both will print about the same with the Rapida maybe holding color a little better. The changing of a coater plate will be much easier on a Rapida so if you are coating many different forms, the Rapida will save time. If you are planning on running many various thickness' of stock, the Rapida gripper system will allow changeover with no adjustments while the Komori still requires some adjustment if covering a large range.
The Rapida 106 is a superior machine to either but the cost is much higher. It would compete more with the LSX40 and the XL 105.
KBA has been out selling Komori and often Heidelberg lately so they are in a very strong financial situation.
I would concentrate on the service in your area. All manufacturers have good service areas and some not so good.
All this said, the Komori is a simpler design and they have always been known as a strong running machine and will likely be down less and cost less for upkeep. I would happy to discuss the project with you if you like.
