Apparently the Alado A2 kit fits the Ballad assuming it has the original rigging - like everything else on Obelix (including cushions, sadly) the rigging is original. I was accurately looking at a Harken MKIV but the price (18.000 DKK or roughly 3.300 USD) seems a bit high. The Alado on the other hand was only 1220 USD (roughly 6700 DKK) including shipping and import duties.
Practical sailor did a review of the Alado back in 2009 which can be found here: http://www.practical-sailor.com/issues/35_2/features/Alado-Jib-Furler_5735-1.html

Once it's mounted and I have had a chance to test it I'll be sure to post a review. I'm even considering doing a video documenting the installation.
