Outer Limits 4x4 Board

Need some air rams for activation of roof lights and rope horns.

I've been quoted $124.00 for air return 25mm bore 100mm stroke. I've got no idea if this is cheap or expensive.

Can anyone help me with this?

This is a basically list price and a rip off.
We would pay about $36 for such a small cylinder.

I will PM you some details on the spares I have
