Looking for recommendations on decent basic iPod (nano) speaker system. Apple hi-fi, Bose and Klipsch iFi probably are out unless great buy($$$), but want to avoid junk. Under consideration are the Klipsch iGroove, inMotion iM7 (?), and Altec Lansing (don't remember model). All in the $150 +/-$50 range. Portability not a big issue. Also would consider a charging dock which would plug into amplified speakers. Heard that one may have issues freezing iPods (don't remember which) and wondering what other problems may exist. please bring it on.
