What Cable Company and what DVR are they providing you? The experience varies tremendously dependent on the provider of the STB. Verizon's FiOS DVR running 1.9 software is very good and in many ways superior to the Series 3 platform you are currently running. In my area, the Scientific Atlanta / Cisco Bright House Networks DVR offers a sub-standard experience to my TiVo.
I think you may want to wait and/or consider upgrading to the TiVo Premiere when the fall software upgrade is released which by all speculation appears to be a significant upgrade.
