USB3 SATA Hard Drive Dock

Hey I need to get a good SATA dock with USB3. Something sorta like this is the best i could find: http://www.vantecusa.com/en/product/view_detail/414

I'm the go to guy among my friends when anyone's laptop fries itself and they want to recover the data off their hard drive. The one i got at the moment is some cheap $10 piece of crap that struggles to maintain 1MBps.

So it needs to have USB3.0 and preferably needs to be able to read 2 hard drives at once, whether they be both 3.5", 2.5" or one of each. Does this exist? Or will i need to buy 2 separate docks?

Thanks
