Still looking for timing belts/cogs

Other Hardware Robotics
1

I'm building something to a specific footprint so I need to be able to buy a cogged timing belt and 2 cogs in the ratios that I need.
I have dissected a bunch of inkjet printers but I will never find the belt length and ratio that I need by scrounging. I have checked Sparkfun and Pololu, but they don't offer much. Does anyone know a source where I can buy small, flexible, fine-pitched timing belts and cogs that match them?

How about SmallParts?

Maybe I should consider o-ring drive instead of timing belts. The resistance I'm turning is very low, but it needs to be precise. I would hate to see it change with temperature. I have tried fine-toothed gears but had trouble that if they are not very very precise gears, then they bind or have inconsistent turning resistance. n
