Digital TV converter box and Computer DVR suggestions

For the converter box, looking for something inexpensive/somewhat robust rather than feature intensive as our first box only lasted a few weeks. I have what looks like this http://www.amazon.com/exec/obidos/ASIN/B001AH8BGW/metafilter-20/ref=nosim/ one, which I bought at Best Buy shortly before the conversion. As I understand it, it's a Zenith that was rebranded for Best Buy. It doesn't look like they're still available, though perhaps you could get one from someone who's bought a new TV since the conversion. My TV is from 1997 (my dad bought it when he moved out, hence knowing) and has only the RCA and coax connections. I've currently got coax going between the converter box and the TV. I seem to recall the converter box manual preferring RCA to coax, but the TV's got only one set of RCA plugs and that's got the DVD plugged in (and it's a big enough pain swapping plugs for the DVD and Wii (and occasionally the VCR) never mind having to swap plugs to watch broadcast TV too).
