These days, frankly, you're best-off getting a TivoHD and asking your cable company to send a guy out with cablecards.
The only problem with that idea is that SWMBO bought this TiVo used at a really good price because it has
a lifetime TiVo subscription with it and that's worth a fair chunk of change, plus a new TiVo would be another few hundred dollars.
I've never been that big a fan of the whole HD experience in any case. The kind of TV I watch really wouldn't be improved much by High Definition.
