Thanks to all who lent me their wisdom and experience. I narrowed my choices to Silca (my intuitive choice) Medai and the Park PFP-2. Of the three I’ve owned a couple of Medai pumps. I really like the simple design, but I’ve had problems that were repairable but pesky. After much deliberation, I went with the Park. It is ugly… but so am I. I think it is going to work well, but only time will tell. Thanks again for all the suggestions!
