With the pending demise of Aereo after the SCOTUS decision, I'm looking for an inexpensive way to get my GF set up for DVRing. She had still been on a VCR with rabbit ears and an OTA box when we met, and I got her a Roku and Aereo subscription for Christmas. She absolutely LOVES Aereo over the old VCR solution, but since it's going away I want to get her set up with an OTA antenna (which I have) and DVR. She's not a big videophile and would only need a two tuner unit. Don't want to spend much so I'm looking for suggestions on older Tivo units that I could find on eBay that would fit the bill. Any help is appreciated.
