CDI
One of the most popular brands is CDI, and Hunter does or used to install them on the H260. They are fairly inexpensive, and can be self-installed without great effort and come with a lifetime guarantee. You will have to have the jib recut and have a UV edge added, but a furler is a very nice convenience. Suggest you determine which CDI size you need and then order it via a catalog company such as Defender Industries - much cheaper.
