Specifications seem pretty much the same, so I guess they are comparable. According to the product page it comes with the board and a shell. No mentioning of cables (that seem to be included in the box of the Pixhawk from 3RD). At moment of writing no accessories seem to be available.
Also no mentioning of 3DR on the product page.

i've had apm boards from rctimer and HK die. never again am i buying clones
Well considering we have been waiting for over two months for a couple of pixhawks from 3dr we would of been far better off waiting for the so called slow boat from china. Basically has ruined our chance of getting Dev 3 done for the outback challenge.
"Specifications seem pretty much the same"
An understatement. I just looked at the two pages side-by-side; they copy-pasted the 3DR text.
so for once we can praise 3DR ;)......
Don't worry there will be other better and cheaper clones
3DR offer is still better. I can't imagine working with only the controller with no cables and all for a first time user...
So $126, but no GPS Rx or housing, no Power Module, no buzzer and no switch. Considering the sourcing and delivery time, it's an unattractive bargain. I'm a bit surprised the cloners are able to undercut 3DR so well on APMs but not so much on Pixhawks.
Clone products are generally becoming unreliable. I prefer buying from 3DR.
