Are you looking to stay pneumatic or is an electric actuator an option?

I use Mitsubishi servos with Festo actuators. Very solid and reliable.

I know pricewise the pneumatic option is probably a good deal cheaper when all is said and done.

depending on your accuracey you could use a inear potentiometer
they can be fitted with the existing cylinder.
then change the Pneumatice to dual 3/2 valves and lock the cylinder
this is very rough but what do you need

Not sure on your environment or exact requirements (electric/pneumatic/hydraulic), but http://www.intelligentactuator.com/ have a large selection that you may find interesting.

but what do you need

I am not replacing or using the existing slide just looking for something close to use in a measurement app. I intend to use the slide to move a laser so as to detect the end of a pipe and than record position to get length. I will most likely need three of these so cost could be in issue as budgets must be approved.
