I've been looking for a good deal for the bionic car dock for a while, and yesterday I noticed that the price on amazon dropped from $59 and change to $41.75, no tax, free shipping, so I pulled the trigger. Link.
If you got in on the $10 amazon gift card for $5 deal last week, it makes this even sweeter.
Note that this is the full package that includes the charger and cables, even the Y-cable discussed on another recent thread. The item description on amazon has pictures of them.
