Nicky is in Devon til tomorrow. Should be home sometime in the afternoon but would expect him to have a kip after the drive. Sure he will get back to you Tuesday when back at work.
I would say you are looking at around £7 to send it, around £7 to have it sent back and depending what Ego it is, prices as Dev said above.
Dont think solanoid and eye wires are covered by any warranty.
Hope that helps til Nicky gets back
