[PJCIII]

I have been given a ~6 y.o. GE Profile 30" gas range by a remodeling neighbor. Only issue is a broken glass top (the owner put his knee through the top trying to take down the cabinets over it). The top seems to run between $220 and $330. Two questions: 1) Seeing that they had no problems with this unit, is it worth fixing the top (is it good for another 4 or 5 years?)?, and 2) can someone who is fairly mechanically inclined replace this part fairly easily (it only seems to involve two side screws on the top, the vent cover screws, and the pans which have 2 screws each as well)?
Thanks guys
