I have the following Tivos: two S3 OLED Tivos a 2-tuner Premiere XL. All three have lifetime. I have upgraded the hard drives on both the S3s to 2T, and also replaced the power supply (bulging caps) with Weaknees replacements. All three units are working perfectly. I am wondering if it would be worth it to sell all three, and replace them with one Roamio (the base model, as I am OTA only) and also two mini's. What would be the pros and cons of such a move? Is it worth it to try to get something out of the aging equipment while I can, and upgrade? What say you all?
