Both have reasonably good ranges of small timing belts
and lots of pulley types.

Hi Andrew,
Thanks for the links.. I tried them before but they have nothing suitable (actually, it seems most of stuff they have is the same as on the site I mentioned).
The main problem is the thickness of the timing pulley (must be max 4mm to fit into the mount) and available diameters of pulleys (the required reduction ratio is 8 ~ 24, to achieve fine enough resolution without going into too fine microstepping.
This is the reason I went with gears.
