Okay then, I'll be the first person to post something
nice about this website

I subscribed a couple of days ago and have found it to be most useful for 1866-1920, finding every entry I have been looking for. As far as I can tell, there is no need to view the actual image for searches within this period (unless you want to confirm that the GRO reference has been transcribed correctly before sending for a certificate etc).
The marriage searches are not as friendly as they could be - there is no facility to enter both partners names like there is on FreeBMD for instance (apart from after 1912, when I assume the maiden name started appearing on the actual indexes). I am surprised by this - it would be very easy for them to implement this on a transcribed database, simply having to match two GRO references.
Outside the years 1866-1920 it works out cheaper to use
www.1837online.com (where it costs 10p per image viewed rather than 20p)
But overall it has been a good six quid spent, and a great aid for my family research!
