Answer partly depends on use intended
RobertWhat do you want to do with your furler and your boat?If the three you mentioned are all you are willing to afford, then you've almost answered your own question, because it seems to me that in furlers, you DO get what you pay for.W/your Santana 35, don't know if you're planning to race. Harken gets a heads up for racing. I love our ProFurl on our Catalina 34, but am not a died in the wool racer. ProFurl does have a racing version.I know this didn't answer your limited questions, but it seems that what the use will be is one of the key elements of the choice you have to make.Good luck,Stu
