One point with the second one though.
After these were converted the owner wanted to use them for engraving on brass but due to the long travel on the Z and to be honest the skimpy build of the Y and Z axis the quality of the cut wasn't great.

They would have been fine for wood or foam in education and with a 12 " clearance in the Z I'm guessing they would have been more for foam or machinable plastic.

Just a heads up before you get too deep into them.
