I have someone considering selling me their TiVo Premiere for $60 which they bought at Best Buy in Jan but have never used. I currently have a TiVo HD on MSD $6.95 and a TiVo S2DT on $12.95. I'd like the Premiere to replace the S2DT. Only think keeping me from this is the $19.99 plan. Is there anything I can do to bring that down? Would TiVo allow me to transfer the $12.95 price from the S2DT?
