Where can one buy affordable push type solenoids?

Hi,
does anyone have a clue about where I can get my hands on a couple of small push type solenoids? The cheaper the better, of course. They are for building some kind of drum/noise machine with Arduino.

I really liked this version hackaday[dot]com/2008/09/25/arduino-solenoid-concert/, so something inspired by that is the goal.

Many thanks/Anders

Some of my favorite surplus dealers have deals on solenoids:

Alltronics, All Electronics, BG Micro, and Electronic Goldmine.

I bought some of the ones from BG Micro, and a few of each of these, to try out for a project I'm working on: tiny one with return spring, and larger one with loose armature. So, if you want to know more about any of them, feel free to ask.

I've got a few extras, so if all you need is solenoids, and can't find other goodies from the surplus dealers to fill out a minimum order, drop me an email, and I can sell you a couple of mine.

Great!
I will check out the dealers. Thanks for your generous offer as well.

Thank you so much!/Anders
