Agreed that the k98 mauser action is one of the best actions on the market. However to addess your concern about mounting a scope and/or the cost of restoring it to original condition. Considering that it's already been mod'd (sporter stock added) then mounting a scope by drilling the reciever or not is a mute point in my opinion. Your only concern mounting a scope (again my opinion) would lie in if you want to bring it back to original. I am not aware of any mounts that would not require altering the reciever in some way other than a scout mount like the one you've got on your Brazilian rifle.
I am not a big fan of sporterizing the milsurp rifles but I do have a few in my collection. My advice would be go sporter and don't worry about mounting a scope to the reciever or return it to original condition and find a scout mount.
Cost is only a factor if you intend to resell it. Cost is not so much a factor if you intend to keep it and have an original piece.. Remeber, value only amounts to what someone is willing to pay.
