I own 2 Dillon 550's. Bought the first in the early 80's and the 2'nd around 2000. If I was starting over, I might consider going with the 650's, but I'm not sure.
I have loaded tens of thousands of rounds on the 550's and never even came close to a double charge due to not advancing. I personally like the manual index feature and it give me a lot of flexibility. I'm not sure the 5'th position would be of great value to me. I love my 550's and keep one with the large primer set up and one for small primers.
And just for a comparison, I have been using a Pacific 366 press for my shotshell loading. Started using it in the early 80's. I have 8 things happening at once, 3 of which don't always occur correctly, and clearing problems with the auto index feature is more hassle than I prefer. Can be done, but always takes some thought.
So I am not auto index. The 550 operation is just so simple and straightforward.
