I've been using the following code for several years and I am very
happy with it. You just quickly store your position (using C-. in my
setting), move somewhere else and then can toggle between the stored
and the new position using C-,.

Of course the keybinding is a matter of taste...

;; suggested key-bindings:
;;(global-set-key '(control \.) 'ska-point-to-register)
;;(global-set-key '(control \,) 'ska-jump-to-register)
(defun ska-point-to-register()
  "Store cursorposition _fast_ in a register. 
Use ska-jump-to-register to jump back to the stored 
position."
  (interactive)
  (setq zmacs-region-stays t)
  (point-to-register 8))

(defun ska-jump-to-register()
  "Switches between current cursorposition and position
that was stored with ska-point-to-register."
  (interactive)
  (setq zmacs-region-stays t)
  (let ((tmp (point-marker)))
        (jump-to-register 8)
        (set-register 8 tmp)))


Hope this helps...
