Cheap bastids don't have to make sense. Besides, I bought the vise on sale! Now find me a $25 profile plate and maybe I'll bite. I spend money, but I always have a problem letting it out of the wallet.
Thanks for all of the good comments on the profile plate. I'll keep my eye open for one, I need to upgrade my bi-focal perscription and get the profile plate and hopefully I will have less eye strain. It's a pain getting old.
