Balljoint - Good Price?

Had loads of play in OSF wheel - (had both sides go within 3 months now)

The balljoint hub are around £200ish from a dealer, I managed to pick one up for £160, how much would you guys expect to pay for it to be fitted?
 
Renault wanted £400 to fit mine (both sides) and they charge about £95 an hour.
Took me about 6 hours to do the first one as It was the first I'd ever done, second took just over 3!
