Could he round off the corner for you? (Then you'd only need to replace the formica strip.)
Mine is made from a heavy desk (like the teachers used to use) with a formica top as well. It is quite slick, but I use the quilt glide... I never even thought about pledge. You don't worry about what that might do to your quilt? It is a good idea, & cheaper too! (more money for fabric!! :D ) I like the weight of the desk because it never vibrates the slightest bit. I placed a table legnth wise along the left side that has rounded corners; that gave me extra work area, and eliminated the corner problems.
Good luck in your quest :D
