what is your experience with a dockstar ?
The dockstar (the original with 3x USB + 1x mini-usb) did cost around 20EUR here in Germany...
for me its better to have 4 USB Port rather than 1 eSATA Port.
The dockstar also has 128MB Ram.
debian Lenny and Squeeze is easy to install via http://jeff.doozan/debian/
some additional Infos at his forum at http://forum.doozan.com/
If you install a real Harddrive (no Flashstick) you can add some SWAP-Space :-)
