Good cheap integrated stepper motors?

Hi,
Anyone know of sources for cheap stepper motors with integrated
electronics?
Maybe that's not a likely combination I suppose, but any leads or
suggestions would be great.
Also, what are some of the smallest packages. Are very expensive
usually? Or cheaper because of less material.
Thanks.

Well, thanks...but those aren't integrated. :)

I guess it would depend on what you want integrated - driver or driver+controller? I'd say you are guaranteed to overpay if you bought your 1-axis stepper controller integrated into the motor. I don't see how it would use much less components than, say 3-axis one. Besides you loose any flexibility should you even require a different interface to the controller. Well, ontop of all of the above I would admit I have never come across a stepper motor with controller in one unit. Sounds like a custom application to me if it exists. Have you checked the usual military/industrial surplus places?

Sort of like this.

I guess they're kind of new, relatively. I saw them in a show so I thought this was a product trend.
I'm looking for store to buy these things. And they would perhaps carry an "existing line". Not really surplus as availability is usually random. But I guess that's better than nothing.

Here's a pretty good video one.

The associated page (go up and down one level on the URL) has the controllers.
You've only to screw up the connectors on the controller boxes.
A small increase in the number of wires in the total automation scenario

Including a controller does what ? That kind of negates using a stepper in the first place. Mabe if you could tell it to move 10 steps from a usb bus ??

I would imagine that the advantages include miniturization and ease of use. Not everyone has stringent requirements of their motors. Sometimes it doesn't matter as long as you can achieve a position without too much "design and forethought". You don't have to know how it works. You just want a black-box.
