Assuming you are going to replace the spheres, why not add in the cost of a pump make your own for £70 (I did a how to once, not sure where it is now) or factor in buying one £100 www.hahsltd.co.uk Ian and Dawn Kennedy are the people to talk to, they are mobile to do the job or will supply recon spheres and pumps similar to the one I made.
