Your price range and expectations for your engine are really what it depends on. If you're not spinning some high RPMs, you may not have the need for an SFI approved balancer. If you are, Pro Products (same manufacturer as the Typhoon intake) sells an SFI approved balancer that's supposed to be a high quality piece from what I've read. They run in the $100 range from what I recall. You may not even need an SFI balancer if you're planning, or have already done a mild build consisting of just H/C/I and a stock shortblock though. There's several of us (myself included) who are just running factory replacements with mild builds. Pioneer is the brand that stands out in my mind as the one many of us recommend for a factory replacement.
