Harmonic Balancers

I can't seem to find a thread that covers this.....I am rebuilding my stock 4.6 3V to eventually reach around 650-700 hp. The new rotating assembly will be internally balanced (like stock), but when I add the SC I am assuming I will need a stronger sprocket and pulley, and that the pulley would need to have a balancer. I'd like to install that during the build so I dont have to do it later. Most of what I am seeing are underdriver pulley systems, which I'm not interested in. I have seen an AFI balancer for around $650, but that makes me nauseous. I'd appreciate any thoughts you can offer
