look at 3 possibilities
Ah, one of my favorite subjects here. Unlike the vast majority of users of this site, I don't like CDI. I have one on the 1995 H26 I bought in 1999. My previous boat had a Harken. There is no comparison in the quality of parts. Harken rules. My CDI has had constant problems and I have rebuilt it several times now. The last time (with the generous help of many HOW contributors) helped many of the problems, but didn't fix them. Frankly the list is too long for this forum. I have found that the parts are not high quality and when I contacted the company directly they were not only not helpful, they were downright rude. And that was the owner. My Harken on the other hand was the highest quality. I rarely had problems with it and when I did they were very easily fixed. The company was 1000% behind their product, even sending me a part I lost (the sail loading guide) and refusing to accept payment. CDI also claims to provide parts and service at no charge, but that was not my experience. At least not with simple advice. There are some issues with Harken, too. They are quite a bit more expensive. To me this isn't a problem because on inspection (and through experience) you clearly get what you pay for. There may be a problem with the luff, however. I don't think Harken's is flexible, making trailering more difficult. There is a compromise. My sailmaker turned me on to the Schaefer Flexible Furler. It seems to be made with nearly the quality of the Harken, but with the flexible luff track. He sells all three, and prefers the Schaefer for small boats.I still have my CDI because it is functional. Barely, but functional. When I finally get so fed up with it that I sink it I'll probably go with the Schaefer, because of the flexibility issue.The moral of this long story is...find someone who sells all three. Get their advice on quality and don't be afraid to spend a few extra dollars for quality that will be headache free.Good luck...
