I want the 2'x4' one. There are TWO forms that the legs come in — a "standard" one that comes in 30" high, and a "new improved" version that's 36" high.
I probably want the 30" high one, for two reasons — 1) shorter should be slightly more stable, and 2) my trunk's inside lip is 30" high, and it would be nice to be able to place longer boards across both the trunk lip and this "portable workbench". (using the trunk lip as a kind of "second saw horse")
the table top:
That first-party top is pretty heavy. TODO — I'm not sure how thick the material is? This video suggests that 1/2" thick is fine for the top.
