Go with ProFurl
Although my 37-Cutter came with that dreadful old CDI, I had installed a ProFurl on my previous boat, a Grampian 30. I had a Hood furler on the boat before that. I have sailed on other peoples' boats with Harken furlers. I certainly agree with the observation about Harken tech support but the ProFurl is head and shoulders above all others I have ever had any dealings with.
