I wrote a function which does just that.  It was inspired by the
Control-Meta-L command from Symbolics' Zmacs editor.  You, of course,
can bind it to anything you like.

(global-set-key "\e\C-l" 'select-previous-buffer)

(defun select-previous-buffer (nth)
  "Like the useful parts of Zmacs' command of the same name.
With no arg it toggles between the two topmost buffers.  With an arg,
goes to the Nth buffer down on the stack, er, ring."
  (interactive "p")
  (let ((buf (current-buffer)))
    (while (not (zerop nth))
      (setq nth (1- nth))
      (setq buf (other-buffer buf))
      )
    (switch-to-buffer buf)
    ))
