When I called GAHH to have them sell a top to me through a local installer, the price was around $1200. I'm guessing your price would be similar.
I'm not sure if this is reasonable to you or not.
GAH does offer discounts to forum members, so click on their banner ad at the left side of the page and contact them, asking for the best price and see what happens.
Best of luck to you on this one... I want a new GAHH glass top myself, but can't seem to find the cash and like others, my plastic window is in great shape
