I've been existing with two S2s and extended basic cable. I've not upgraded to any TiVo HD, as I didn't want to get further locked in to the cable company. Also, the pricing complexities of various TiVo units causes me to put it off for another day. I'd like to get two new units (well, new to me), capable of HD, used for OTA, but most importantly, I want to be able to simply change the TSNs online so that I maintain my $12.95 and $6.95 pricing. I can't do that with the $99 Premiere units. What's my best option?? Thanks.
