Wow! Discontinued already and I haven't even installed mine into my system to replace my 975. Yes, my 976 has been sitting in my closet since I bought it. Procrastination plus a very busy last year before retiring from 3M Company after a great, fun 38.75 year career. I will soon finally install my 976 - hope it doesn't have problems as it's now out of warranty.

"No Mr. Bond, I expect you to die!"
