Leak in power steering

[iprd1956]

I have a leak in my power steering. My car is a Citroen Picasso 54 registration
Is it worth getting it repaired and any idea of the cost? Also are the leak stop repair solutions you can buy worth using?

1) What engine have you got (post up your VIN as there are different power steering systems depending on engine)
2) Where is the leak coming from?
3) Pictures would help.
