I am looking for an inexpensive solenoid. It needs to be a pull type

In my practical experience, solenoids are not a good choice for moving
something 3 inches. They use alot of power for a given force, and
typical stroke distances on available, inexpensive solenoids are very
small. They are very quick, though.
Without knowing your application, available energy sources, speed and
force needs, etc., it's hard to recommend something else.

Instead of moving the load directly by the solenoid, you might consider using a
cantilever, such that the solenoid only needs to move an inch or so. The lever
extends the movement to the required 3 inches.
Surf the web; search for solenoid for some decent selections and prices.
