Sqeezebox 3 anyone?

My current media player is a D-Link DSM-320 (a few years old now).  It sounds OK, although I don't have any other media player to compare it with and What Hi-Fi have never reviewed it or even mentioned it as far as I know.  Ethernet-wired to a reasonably fast Dell PC running Windows XP Media Edition its menus are slow, clunky and often fall over.  I'd like to change it - ideally to a Squeezebox 3, since that had a very good review sonically and is one of the few media players with a digital output rather than line-level. 

I have no interest in ripping my CDs, I can play them if I want to hear them.  Instead I look for odd tracks/songs I like that may now be deleted/discontinued as discs but are downloadable from the legal sales websites.  Currently I buy tracks from the Tesco download site - the D-Link can play these DRM-protected WMA files but it can't play iTunes ones.  I would be happy to change to buying tracks from iTunes as long as any new media player can play them through my hi-fi better than the D-Link can play WMAs.

Actally, my ideal solution would be that the Sqeezebox 3 plays DRM WMA.  However when I e-mailed them about this they seemed to think that no devices could play DRM files and when I told them that even the old D-Link had had this capability for a couple of years they were surprised.  Come on Slim Devices, stop living in a time-warp and get up to date!  

The What Hi-Fi review of the Sqeezebox 3 said that it could play Apple Music Store files with a bit of "jiggery-pokery".  Can anyone tell me what this would involve?  Is it a practical proposition for day-to-day usage?  Does it cover all the high-quality file formats downloadable?
