It is really tempting to keep and use the steppers that are already
set up. I just can't get a straight up answer from the archives
as to how well it may perform. A bunch of people were only able
to get 60 or maybe 80 ipm rapids before reliability went down the
toilet. I wonder how well a modern NEMA 42 stepper would work
in comparison to the original 25+ year old steppers. The technology
put into them must have changed sifnificantly since then. If I buy
stepper drivers
to use with the factory motors, then I am comitted to steppers.
What does a modern NEMA 42 go for these days? and are they better
than the original ones? These are questions I need to figure out
before comitting to steppers.

Maybe servos are the safest bet. Many frown on them because they
think they cost more, but there are servos available on e-bay that are
pretty inexpensive ($250 or less per axis with encoders)
