I like 'slick copy', ie., copy without needing to select:

Then, you can duplicate lines with:
M-w C-y
Which is very natural.

Something quick and fairly dirty:
(defun comment-and-dup ()
(interactive)
(save-excursion
(beginning-of-line)
(push-mark)
(forward-line 1)
(let ((str (buffer-substring (region-beginning) (region-end))))
(comment-region (region-beginning) (region-end))
(next-line)
(insert-string str))))
Best wishes,
Dirk.
