If surplus motors are okay, here is a place I've often used that has decent motors, a good selection, reasonable prices and fine service, here in the US:

I would love to change the world, but they won't give me the source code
People say that if you play Microsoft CD's backwards, you hear satanic things, but that's nothing, because if you play them forwards, they install Windows.
I spent a minute looking at my own code by accident. I was thinking "What the heck is this guy doing?"
If you are not picky and willing to put a little effort into it,
On the web, go to your local freecycle group on·Yahoo or your local craigslist, and ask for peoples broken printers and scanners, and cd/dvd drives.
You'd be supprised how people are thrilled to get rid of this kind of·'junk'.
True, you never know what kind of stepper motor you will get, size and type, some not particularly suitable·for robotics, but they are free if you are willing to do some scavanging. I have gotten dozen$ of stepper motors this way, all good as new, all kinds, bi/uni-polar, tiny, med, large, plenty of misc gears, switches, power supplies. A gold mine of parts really, all free.

Particularly older 5.25" floppy drives have nice steppers with worm-gears for positioning the read/write head.
The ones in 3.5" drives are somewhat smaller, but also usable.
(and these drives you can easily score a dozen or three of almost anywhere.)

The first one on the list was the kind I got, couldn't pass up 99 cent stepper motors.
