Hmm, I'm a little late to the thread. Did you end up making one?
Some students are turned off by the school jointer because the sole changes almost daily. They are easier to adjust, but be sure to seal the body very well, or you will be adjusting almost every jointing session. In that video you can see the jointer body itself is actually popping at all the seams because it was never well sealed. So shellac it a bunch once you've made it, especially at the mouth where there's a lot of endgrain exposure, and it will be much more stable.
