Unfortunately, my experience was not so great. My mother has had the worst luck with tivos... she thinks she's cursed not to have one.
Years ago I bought a 14 hour unit on clearance at Circuit city for her, when the $99 we paid was a GREAT price. it died within a month. Unfortunately, my mother has always had a thing about returning stuff, even if it's not working, and at the time lived two states away from me. I couldn't get the unit from her until after the 90 day warranty was up.
More recently, I bought her a HUMAX T800 in april of this year. Immediately she noticed problems with audio cutting in and out, but we thought it might be her receiver since she hadn't been using it before. When I was next at her house, I connected the tivo direct to the tv to find the problem indeed with the tivo. We called for a replacement, and shipped the old unit back at her expense. Humax lost the unit, and it took a month and a half and many phone calls to get them to ship another one out to her, a refurbished t800.
When she connected this unit and ran guided set up, it got stuck during the cleanup phase of the initial call, and wouldn't go any further. It was also making loud noises, indicating a bad drive. I called humax, and this time they did an advance exchange because of our previous bad experience. However, it didn't seem like this rep really knew what he was doing... he asked several questions more than once, and didn't find her info in the computer, and had to call us back 3 times for more information.
A few days later, she received her new tivo, and to our surprise it was a DRT800, not a T800. I expect this was a mistake on their part, but perhaps it was a gesture to apologize for all the trouble... who knows. She's glad to have the upgrade though.
The problem now is that even this DRT800 isn't working correctly for her. We have it hooked up, and functional at the moment, but the RF output doesn't work. I hate to call and get it exchanged again after all the trouble we've been thru so far, but I also don't want to keep a defective tivo... who knows, some day she may need to use the RF output. And, if the rf out is bad, it's hard to say whether anything else might be wrong with the unit that we haven't found yet...
Overall, it's been a frustrating experience with HUMAX support. It seems as though they have very poor quality control on refurbished units. Almost as though they plug in the defective units, and if they power up okay, they mark them No fault found and ship them out to some other poor customer...
