I have an extra Motorola Laptop Dock for a Raspberry Pi available for sale. $35 firm. I purchased this one used from ebay a couple of weeks earlier, then found one for a little bit more that was new, still in the box, and has a power supply.
The Laptop Dock (Lapdock) that I have for sale does not have a power supply and it has some scratches on the case, possibly from the removal of a sticker.
If you can fashion your own power supply for it, you can use it as the HD display, keyboard, and mouse for your Raspberry Pi with some simple cabling hacks. Without it, you would need a usb hub to connect the mouse and keyboard and you would have to lug around a HDMI capable display.
Email me if you are interested.
If nobody wants it locally, I'll put it back up on ebay.
Also, if they are still available, I can show you where to purchase a new one for $50 shipped instead.
