Bread-Bakers v006.n013.2

We're making a lot of dense whole wheat bread, and enjoying it, but we're
not eating as much of it as we ate of the store-bought bread because
slicing it is such a chore (and messy, too!)

I think it would be worth our while to invest in a serious slicing appliance. 
Does anyone have any suggestions, and do you know any vendors? 

What is the state-of-the-art in bread slicing technology? I'm picturing some
sort of box with slicing guides, or some sort of electric slicer...

thanks Betsy
