Old thread, but rather than starting a new one I might as well ask how you got on with your search?
I didn't realize how happy I was with my Squeezebox Radio until I sold it, and I didn't realize how difficult it would be to get something as good if not better. I'm currently using a Sangean WFR-28 and it's a poor substitute with too many annoyances to list here. The Grace radios look similar to the Squeezebox but i'm wondering if they are as good. The SB had nice little touches like auto-dimming display, a display that showed the current program (not just the station), and direct-on by pressing a preset button. The Sangean has none of these... or indeed any nice touches whatsoever.
