We've never had a problem using the AL equipment in JD combines, new or used. It WAS nicer when JD had the cutout on the clean grain for the moisture tester, but I JD has perfected a better way & now test the grain elsewhere, so we have to cut a hole in the clean grain. That's about the only "problem" we've ever encountered. Certainly nothing electrical in nature.

You're still using your PF3000..that's good-but they do have a fair resale value, I think.

We're very happy w/AL Insight for past 2 yrs. It works fine & flawlessly for us. I realize some folks have problems w/various gadgets, but Insight has been fine.
