Cost of a new Cam chain?

[HazzaBui]

So a Tuesday evening spent pushing my bike 4 miles home, rather than enjoying a blast down some nice twisties, and it's looking like a new cam chain is on the menu for me.
Anyone had to have this done recently that might be able to offer a guide towards the pricing?  It's certainly not something I was hoping to have to pay for, after getting a ton of other stuff done last month, only to have to get the engine opened up again for this job.


Any info much appreciated!
