Anybody know of one?

Yes, you can try Screaming Frog. Free up to 500 page crawl, or you can buy the pro version.

I'd 2nd Dan's response with Screaming Frog. Been using it for a number of months now and love how easy it is to use. I have the pro version which gives you the option to limit crawl depth and what it crawls etc but the free one is great too.

I would prefer to use the Moz Crawler research tool. It does come with a extensive report.
