Essentially identical in weight. One comes with a built in box, one doesn't. One uses a 4 inch Technika board, one used a 6 inch wooden board. One is new, one has been proven for 70 years. One is about 1500 bucks for a nice kit, one is 2500 bucks for a stripped model with lensboard and case.
And no, the Deardorff is extremely solid.
