It won't pass analog, but the Zenith DTT900 has worked great for my parents. I like it so much that I'll probably be getting myself one over the summer. Be forwarned, though, that there have been problems reported with the audio. I have not observed these issues.
Otherwise, if you're patient (and the cards last long enough), the Echostar TR-40 is coming in June or July and will have analog passthrough. It's also going to be $39.95, so it'll be next to free. Little else is known about it.
Hope it helps you out.
