I really like the overall look and feel of the Nexstar MX. It's one of the best little drive enclosures I've used. I don't know if adding eSata is worth doubling the price from the previous version, but it does allow for much more than a doubling of speeds. I have been loading the MX on my PC using eSata, which takes very little time, then I access it on my laptop via USB 2.0, as my laptop does not have Sata, let alone eSata. Since I am not going to be transferring all the data off to my laptop at once, the USB 2.0 is fast enough for things like movies and even games.
