Why do you consider FSLaser as a "real American option"? FSLaser sells Chinese machines only (with a juicy re-seller markup). All of their components are designed, developed and manufactured in China, by Chinese companies and for the Chinese market.
- If you want to buy machine designed by an American company look for Epilog or ULS (Universal Laser Systems). Both make top quality machines but as you may expect they are significantly more expensive than the Chinese options.

Why would you want to tweak and rebuild an imported machine? The whole point of importing from China is that you can get a custom configuration build per your exact specifications and requirements. Most Chinese companies would offer to you a long list with available options to choose from.
Do you need the machine for hobby or for real production?
