For pneumatic pistons, there are a variety in H&R Company Catalog.
From about about $6.00 to $14.00 each.  Stokes from 1/2" to 14" strokes.
You can get a catalog from them:
	H&R Company
	18 Canal St., P.O. Box 122
	Bristol, PA  19007-0122
	1-800-848-8001

They have a LOT of motors and other things I have not seen in other
catalogs.  They also have 12+ volt solenoids, and a computer printer
assembly with 2 impact solenoids.  Electronic Goldmine has another
printer head assembly with TINY solenoids.
