Let's try to answer your question instead of lecturing you Steve..............
Like John, we had a CDI furler on our Catalina 25 and it worked fine "most" of the time. The issue was with the PO, not the furler itself. I'm not sure what he was doing but we discovered a small kink in the forestay that was causing the issue. It was taken care of and the furler was fine after that. On our Catalina 27 we found a used furler from a similar vintage C27 at a sail loft in Florida. I sent them my hank-on 160 which they modified for that furler and then shipped everything to us up on Lake Erie for a fraction of what a new setup would have cost. That boat has since sold two more times and lives at a marina next to our club. Same furler and sail. You might do a Google search for used sails and check websites, as I recall it was Atlantic Sail Traders but I couldn't swear to that 100%.
Lastly, if you decide that you really do want a new unit you might take a look at the offerings at Sailcare in Ford City PA (they have a website as well). Jerry does a great job in his place, they can give your sail a good cleaning, modify it to the furler you choose and ship it all down to you in Charlotte. We have had the sails from both Catalina's, our Islander and our Island Packet cleaned at Sailcare and I swear each time they arrived at the house I thought Jerry sent us new sails by mistake.
I totally understand sailing on a budget and not wanting to invest big dollars in a small dollar boat (you'll never get them all back when you sell by the way). There are a bunch of ways to get where you want to be.
