That'd be your best bet. My own iRiver player/recorders (H1xx, 30GB and 40GB) use 1.8" HDs. Or sell them now while they have some value ($5?). I remember when a 1GB 3.5" HD cost $1000 (a dozen years ago or so).Find an older player that used 2.5" drives being sold cheaply due to a bad drive? (Ebay, etc.) I know the Creative Zen Xtra series used them because I still have the drive from one here.
