I have a smiliar 1,25" 0.5x astro focal reducer, bought for a few bucks on Ebay
My results are better (at least much less CAs - but I guess that depends on the lens used on it), but I've only tried on a mirror lens lens so far (500mm fl - astro focal reducers are generally optimized for long focal lengths).
I wonder how good these more modern MC 2-element focal reducer would work http://www.ebay.de/itm/0-5x-Focal-Reducer-2-for-visual-observation-photography-TSRED052-/370729192906?pt=UK_Photography_Telescopes&hash=item56512e8dca compared to the new expensive focal-reducer-adapters.
