I was just wandering around a few sites and realised that http://labs.familysearch.org/ has lots to offer now. If you scroll down there is something called England jurisdictions 1851.
You can search a parish, say Rowley Regis or Great Ness (for a post on this board) and it will show you the surrounding parishes. Great if you are not so hot at geography
I've used the Record search part a bit recently as it has some census stuff for America, immigration records etc.
They obviously have a lot of new projects coming on so it is worth having a look every now and then.
