Which Tivo Setup Will Replace Genie

This may be covered already but I was not able to find the info I am after in a search of the forums



I currently have a Directv Genie HD DVR in one room and a small Genie mini HD remote unit in another room. They talk via the whole home DVR network. I like the overall functionality but I want to get rid of Directv. When I do that I want to replicate the functionality of the Genie stuff with Tivo hardware. I will only need over the air on the Tivo (no more cable or sat stuff - too expensive).



So, can you knowledgeable folks tell me what model of Tivo HD DVR and remote "slave" unit will let me replicate the Genie/Mini setup I have now?



Thanks!
