I went with the AK-Models. I have no idea if they are better than the others, since I only ordered from one cutter.

So far two of us have talked Mark into letting us buy the plans and DWG files for the laser cutting. My guess is that it is not on his web site because we are talking about the prototypes for a model that has not flown yet. Still I am having a hard time waiting for the kit for my second work bench (MY BUILD TABLE) to show up on friday, so I can really start the building.
