For those who have grinders with battered platens, or if you have a cheaper Sears, Grizzly, etc. Patton Knives gave me this great tip. Take the platen to a local glass shop and have them attach a piece of 1/2" thick fireplace glass to the platen. Have them cut the glass to cover the platen and round the edges... Patton mentioned the glass company will know what adhesive to use. The fireplace glass is super strong and doesn't heat up like the steel and should last years without having to be resurfaced. The total for glass and adhesive runs about $7.00 here in Boise.
