Jeff, I read somewhere that the Taig mills can't really take advantage of motors larger than 140-160 oz/in. On that basis, I was thinking about buying the 205s from HobbyCNC. Is this really likely to pose a problem compared to other motors or systems? I should add that the projects I'm planning will require cutting a few radiused holes in 0.5" (13mm) aluminum plates, probably 2-3" (50-75mm) diameter.
The second drawback is mid band resonance, Gecko's don't have that issue.
You may need to add harmonic dampers to your steppers to obtain the performance you are looking for.

I'm not familiar with those. Is the dampener a digital device that works with the pulse timing/width, or some sort of resonant LC circuit? Do you have additional info about this (maybe schematics)?
