Where can I find my piano stool ?

I have recently purchased a piano. But I realized I would need a proper piano stool for my posture. I also need the stool to have storage and to be a duet.
Does any body else think piano stools are too expensive !
I found one worth more than my piano !
can any body link me to a piano stool, worth round £0.01 to £99.00?
