I recently bought a Premiere 4 (3 weeks ago) used for a great price. I have since upgraded the HDD to 2TB. I am toying with the thought of selling it and buying the Roamio Plus. I know that it has an extra 2 tuners and the HTML5 interface is a bit faster, however I am not sure whether or not it is worth selling it and spending the extra money to upgrade. I figured I would ask you kind folks since I'm sure someone was in the same situation. Any input is much appreciated!
