4k/8k and a home made paddle with cro-ox pasted on one side. the 4k/8k will take care of you unless you need a bevel set. (it will then too, but it may take a while)
chrisl's free/cheap film may be the cheapest way out of the gate, but you will wear the film out. the norton is just tried and true. i went another route and ended up getting a norton combo.
good luck..
