Flashforge Guider II vs Craftbot 3 Dual Head

[jblc]

I'm looking to purchase either the Flashforge Guider II, or Craftbot 3 Dual Head. I'm also open to suggestions for what may be better at the same price ($2k USD).

• It'd be for prototyping parts that will eventually be CNCd in Aluminum, and for making small nylon gears directly.
• Each printer has advantages and disadvantages: 1 vs 2 extruders; removable bed vs fixed; full ventilated enclosure vs open; and semi-auto bed leveling vs fully manual.

If you could get one of them, which would you choose for your use?
