Rich_K's remark (there arenot many good points) reminds me of my usual reply to the question of "in your opinion what's the best lift truck?"
I always say; in 35 years, I never once had some end user call me up and say, "Come on over I have a really good truck to look at" so; a really good forklift is one _I_ have never seen. Every time I get a call it is along the lines of, "We have a problem we want to share with you".
In my not so humble opinion, service techs should not claim to know what is really good, just what is it that goes bad.
