By getting an HD TiVo box, you're at least sticking your foot in the water... maybe not a plunge, but it's not a complete avoidance either
If you weren't thinking of HD down the road, I'd call it overkill, but since you are it might be a good investment.
If you're wondering whether an HD TiVo will work with an SD TV, of course it will. That's what the composite and S-Video connections are useful for.
