I don't know much about red combines as our family has always had green, currently a 9660 STS. I told the local red dealer to price us a 7120 and 7088. How do the two compare for reliability, performance, servicability, ease of setting etc.? I've spent most of my time researching Lexion verses the Deere. Since color doesn't really matter to me anymore I thought I'd compare the red as well. Is the 6088 smaller than the 9660 STS? Maybe I need to look at it as well?
