In post #5, I mentioned that I have an old Harmony 520 and that if I had to, pick up a used Pronto 1000. Seems like the most popular code sharing is via Pronto hex, so I bought a used TS 1000 on ebay and waiting for delivery. I do not use the Harmony very much because it does not have enough buttons. I have a Sony RM-VLZ620 as my main remote because it does everything I need it to do. I plan on using the Pronto to teach the ir code to my Sony.
