I'm glad to see that accurate milling is possible on a good (relatively) inexpensive DIY/kit CNC!
Not to threadjack, but I'm also a newbie to milling machines, at least when it comes to building them. I have a good amount of experience in using the LPKF S100 as a student to fabricate various through-hole and surface-mount PCB's. I'd like to build a PCB CNC machine to do the same, ideally for less than $500 (cheaper is better). It is purely for hobbies.
How does the Fireball compare to this Zen Toolworks CNC kit:
