Replace stock Harmonic Balancer?

I'm wondering if there is any benefit to going with an after market one instead?
just in case you're not convinced yet - YES, there are many - IMHO - #1 being your personal safety, #2 being protecting the investment you're making in the engine. Even a straight stock replacement would be fine. (if you're not looking to hit a race track with it) The one you got there is plumb wore out.
