Keep in mind that the 1080 is older than the 1084... So it's likely to be closer to it's death than a 1084. I had a 1080 that I got with my original 1000 back in 87 or so.... it died a bizarre death before all of my newer 1084s. On the other hand, I never saw a 1080 in the shop, lots of 1084s though.
