Need a Harmonic Balancer. Which one?

I've been using Pioneer's SFI internally balanced balancers/dampers on my internally balanced race 360's for years. No problems. Here is a link, but it doesn't hurt to shop around for pricing.

The ad pic looks nothing like the actual unit. But the actual balancer appears to have all of the factory dimensions for proper pulley attachment and alignment.
