Replicating TI's overpriced Op Amp Evaluation Module

I just run around my sources with the BOM, not even trying to find the cheapest solution, even counting the shipment cost, calculating only one board, and the cost would be around 50 bucks. Even less if I put some research effort into it.
So, lets the journey begin. I'll replicate this kit.
And finally...
After some fighting with the Fedex/Customs Office, it landed on my desk:
Let the learning begin...
I started to work on this project, replicated the schematics in KiCAD, created the PCBs for the OpAmp inserts, and partially designed the main board itself.
As you may know the project found it's way to the Hackaday blog itself:

I don't know if somebody at TI read what I wrote, but this came today in a newsletter:
So, mine is on the way to Budapest:
I payed ~$60 for it with shipping.
If you need it hurry up, while it lasts.
Notes:
First: The project is officially canceled - I've many more things to do
Second: Great thank you for Texas Instruments, for this offer!
Today I got all of the Operational Amplifiers required by the board, and I also made a handful of breakout boards for the SOIC-8 packages.
I just replicated the original schematic from the product documentation into Kicad, to be able to design a new board.
I also commited the KiCAD files into the repository of the project.
The schematic is still shaky a bit, because there is some discrepancy between the drawings and BOM in the documentation, so I've find out which is correct.
