I stumbled upon this Startech Portable Dock/Cloner/Duplicator on Bestbuy.ca for only over $16.
Startech Portable SATA Hard Drive Duplicator With eSATA and USB (SATDUPUE) : Storage Accessories - Best Buy Canada
Other sites are selling it for a higher price up to more than twice this price. So to satisfy my curiosity, I purchased one. If it doesn't work, I can always return it back to the store anyway.
But after testing it to clone a Mac OSX and Windows OS (standalone without a help of a PC), this is now a keeper. It gave a smooth boot up on any OS. This will become handy in the future like perhaps copying a dying drive or just a test dock for an OS (boot up via eSATA port on it). It also has USB port. Very versatile little thing.
