I just found this and can't find a mention of it on TS (may be just my brain this morning) so thought I would mention it. This site:
http://www.bmdregisters.co.uk
has a free general search, which is fine unless you are looking for a very common name. An advanced search uses one credit (50p) and viewing the image uses 5 credits (£2.50). This site is very helpful for us folks whose ancestors left England for religious reasons. Several of my Quakers and Puritans have popped up!
