Our Seaward Princess range/oven combo finally bit the dust. Replaced it with a glass cooktop--no oven. Don't need it. Now the admiral was suggesting we replace the countertop and adjacent surfaces to bring the ol' gal into the 21st century. I'm able to template the counter and hopefully have it built by a company and then install it myself. Has anyone done this and are there any tricks or traps of which I need to be aware? Thanks.
