Be very careful about buying a Xcarve or Shapeoko. They are both drastically underpowered and not very rigid. Rigidity is one of the most important factors in a CNC. If it's not rigid, you cannot get repeatability in your carve. I gave away my Xcarve 1000 after a lot of frustration. The gantry flexed so much, cuts were not reproducible. It only worked when I made lots of minute passes.
The best words: Buy your second machine first. I bought a Axiom AR8 Pro+, and couldn't be more pleased. Probotix and CNC Router parts are worth looking at. Plan on something with a spindle, routers aren't made for CNC.
