Hi All- I'm a newcomer to these parts... Howdy! I've never owned (or even used) a TiVo before, but am excited to delve into the world of TiVo. That being said, I'm clueless as to what a refurbed S3 box would present to me in terms of problems, software issues, etc... I would really prefer a S3 - and can get a refurbed S3 (with 1 year of service) for about $655. I could also go the new TiVoHD route for about $180 less ($450 with 1 year of service), but it's a new box. Any suggestions? I'd love input. Thanks!
