I've purchased three of the Auber kits over the last month or so. I bought them because I wanted the thermocoupler they sell and at the time it was on sale. They use the latest board, but you have to go with the thermocoupler. I didn't buy the case or RPi so I can't say if it comes all put together. They are easy to talk with so just pop them an email.
I find that they are not too careful when soldering the jacks and I had to touch them up before it would fit into the cases I printed. One of the three, the four way button didn't work, but they were very easy to work with and replaced it without issue.
For the one I built that didn't need the thermocoupler I bought the kit from Bryan with the RPi. You won't find a better deal.
