Where can I see Everwood?

I am a huuuuuge fan of Everwood. Or Our New Life In Everwood as it was known here in England. I watch I think up to the third series? maybe, I think this is where I last saw up to. Up to were Bright falls through the window and hits his head etc?? I know that they used to show it on ITV and its now being showed week days on E4. Was wondering if any one know where or if all the CDS are actually available anywhere? I can only seem to get the first season?
