I agree with Squid. I'm on my third TR-99. It really is tough to get the TR's unpluged and in green oat straw you almost always snap a beater belt. The CR's are comparatively easy to unplug and hardly everbreak or burn a belt. The electronics are very reliable and test equipment is neeed to check um out. All in all the CR's have a lot going for them and have been out since '93 and many bugs have been worked out and improvements have been added. I really like the ease of getting to the concaves and checking things out. I leased a CR940 two summers to run with my TR-99 and the machines both do a good job, but the future is with the CR's. In recent years we have seen excessive wear on augers etc., but we must remember we are putting more grain thru them with the increased HP.
