The so called control cos in my area[NW]are going by the wayside with thier cumbersome high priced service.The smaller groups with the now relocated techs are kicking butt in the small and medium mkts.Siemens has got to be the worst,the others have resulted in selling engineering and parts.
Sort of the same thing in our area , but with SIEMENS doing a good job. Around here it has always seemed that the big companies Honeywell , Powers ( Siemens , Johnsons ) have been on 5 year cycles from top notch to being the pitts. They restructure and the cycle starts over.
Smaller companies seem to come and go depending on how they can weasle into the Goverment work , when that comes to an end they chase the commercial work then seem to fade away.
