Philips DSR6000R DIRECTV Receiver with TiVo Service
If you work nights you NEED this.
Many of the other reviews has said already just how great TiVo is.  Let me just add this:  If you work any kind of night shift, this will allow you to once again have a normal tv experiance without the hassle of a vcr.  TiVo has changed the way we watch tv so much that we are going to buy our second unit soon.
