I've been using the analog xitel hifi link for a few months and so far I am pleased. The obvious mp3 sound quality drawbacks are more than offset by freeing up access to my over 400 cds which have been limited to a 5 cd changer up until now. You are pretty much locked in to what you can do...
I'll add another recomendation for the Kenwood
HTB system Picked it up for my parents and was quite
impressed. It is available in a lot of B&M stores also.
