I'm looking to find a part that would allow me to move a lever a few mm (2, 3 max) from one position to another. Idealy, it would stay in it's last position without needing to hold the power on.

It's to open/close an iris.

Oh, and low power, reasonably available, and cheap too :-)

A normal RC servo maybe?

I've seen solenoids that do exactly what you are talking about (an iris), but I don't remember the mfg.

I suggest looking through a McMaster-Carr catalog under "solenoids". Also try a google search.

This first one here :

Looks primising, I'll have to call them to see if it does what I think it does :D

Only problem is that it seems to take 24V, do I'll have to figure out a way to make a short pulse of 24V using something ridiculous like 3V.

How about using old CDROM device mechanism? Not sure if it fits your needs, but it has a lot of useful parts. I had to build some valve - it worked perfectly!

I would try also a worm-gear, which can be extracted from cheap little toy cars.
