Brian,
I agree with Hu...Dung, if your not pushing the machine (which it will take) the quill is fine for most work. That is where the cleaning and working of the way's comes in. Your 1000's are not overkill at all.
As for the Ball Screws, I prefer the Thompson (you can get them thru msc) because of the nut design. Getting near 0-Backlash is cool! You can look around, some sell the balls with the center yoke all in a package, it might be worth looking into, but can be pricey!
You can always add the third axis later on but plan now. If your looking into boards, you can get some fine boards with the high amp ratings in 3 axis in some cases cheaper than two stand alone drivers.
Good luck man, where are you located? I am in Tampa Fla area?
