I agree, a hipo balancer isn't needed unless you spin it over 6000 often, or sustained revs over 4500. For a good rebuilt, call Damper Docs. Good product for the average application, at decent prices.
Several years ago, a few forum members got together for a group purchase and had a company produce a special run for us. I won't mention who, but will say mind is still sitting in the box it came in and was never installed. It looked really pretty, as it was billet aluminum with a satin finish, but my biggest issue was no provisions for removal. It was completely solid across the front face and I was afraid to drill holes in it.
