I upgraded to the Series 3 TiVo last month and then immediately upgraded to a 750GB hard drive. I would highly recommended upgrading the HDD if you want to record any significant amount of HD material.

This was at the tail end of an unplanned complete overhaul of the home theater system. It started with a 970, in ceiling surrounds, in wall back surrounds and a new TV. This was followed by the irresistable urge to upgrade the DVD player to the Oppo 981. After this I saw an unbelievable deal on new fronts and a new center channel, and finally I decided to replace my old HSU sub with an LFM-1 Plus and SMS-1 (in transit).

I wish we could afford a sweater for Christmas next year but it looks like we'll have to sell the kids for medical experiments to make ends meet. :-)

Luckily I was able to sell most of my old gear and offset some of the expense.

Anyway, Just wanted to say enjoy your TiVo.

Cheers.
