Basic Cable and Upgrading from Tivo S2 - Best Options??

My Mother lives in a retirement home that has basic cable, e.g. no CableCard required to see any/all channels. She doesn't think that will change anytime soon. But who knows... Her Tivo Series2 died a horrible death last night (RIP), so she needs something new. Since it is unscrambled cable now and I guess could go to digital at some point down the road, I didn't know what would be the best replacement for her: Roamio or perhaps a Premier model?



Looking for options so I can look for her a replacement that will work now (basic cable) and potentially down the road w/ digital cable as well.



Thanks in advance.
