There are lots of options.
Turbo-CNC is only about $30.00 and will allow you to use a lot of
variations.
considder timing belts and pullys to change the ratio.
A 2:1 belt reduction will offer half the range or double the
accuracy. A few minutes with a spreadsheet will yield all sorts of
options.
and, if you are off 0.001" then the 'odd' steps are not really a
problem.
