I have a 2 Premieres now (plus external stream and moca adapters) but have been getting itch to upgrade to Roamio for one of the units (can pass it onto a younger brother). Was about to buy the Pro when Amazon had it for $433 but just missed out (now it's $530). Have been now thinking to maybe just buy the base model for $150 and upgrade to a 3 TB hard drive (seems to be approx $130). So 280 vs 530 seems like a no brainer. Before I move forward I want to make sure that I understand what I am giving up. As far as I can tell, the speed and performance of base model is same as pro, with the cons being: 1. No internal stream. But I have my external stream so no loss in my functionality. Only negative is extra clutter. 2. 2 less tuners. But as I have lifetime on my other premiere not a big deal as I still have 6 tuners in household. Granted if premiere dies then I'd maybe want to replace it with a mini...but even so I don't think 6 tuners for me is crucial. 3. Warranty issue if I replace my drive early. I can always wait the 90 days before putting in new HD. Anything else I'm missing? I'm most concerned with performance and snappiness of menus and such that people rave about so want yo make sure I'm not sacrificing that with base model roamio. Thanks!
