Other conversion options are:
1. Having Wheels Manufacturing machine a 9-speed (nine, not a typo - they add an 11 to the end of a cassette starting with a 12) Ultegra or Dura Ace cassette into an "Accelerator 10" conversion for $50 + shipping. Note that you'll end up with an 11 starting cog, with the options being 11-21, 11-23, 11-25, and 11-27. Also note that the conversion can only be performed on cassettes with the largest cog on an aluminum carrier, since they machine a recess in the non-drive side of that to get the wider Campagnolo spacing on a narrower ShimaNO free hub (this is what gets in the way of converting a ShimaNO cassette which starts with a 13 cog because ShimaNO makes those by using a loose cog big cog).
2. Buying an IRD conversion cassette. 12-23, 12-25, and 12-28 flavors are available.
3. Buying a Marchisio conversion cassette.
(I looked at this mess when considering running an original Powertap hub)
