They are kind of small, aren't they (?); at least compared to today's duals. My 9600 has duals, too, but they are a "little bit" larger!
I considered buying the ol' 55, just to have it around since we used to run one on our place. After a bit of thought, though, I decided against it. I do not have room for it in the shop, and after a while, it would be a challenge to keep it running and in good shape.
