Tempered hardboard is very different from pressboard, though try convincing the salesfolk at the Borg of that.

Masonite is the premier brand for hardboard. This Chicago based company makes the best stuff. Their "basic" hardboard is as good as most companies' "tempered" hardboard, and true tempered Masonite "Duron" is about twice as hard as that.

Anyway, we'll see what comes in the truck on Friday.

Cheers
