I use the US Ancestry.com version and have found it a wonderful resource. Indexed on all names, not just head of household.

For some reason, they don't have the IOM part of the 1901 Census... Maybe it will come along later.

I'm always glad to do a look-up if anyone needs it.

Here's what I have access to:
1871 England Census (images, partial every name index)
1871 Wales Census (images, partial every name index)
1871 Isle of Man Census (images, every name index)
1871 Channel Islands Census (images, every name index)
1881 England Census (images, every name index)
1881 Wales Census (images, every name index)
1881 Isle of Man Census (images, every name index)
1881 Channel Islands Census (images, every name index)
1891 England Census (images, every name index)
1891 Wales Census (images, every name index)
1891 Isle of Man Census (images, every name index)
1891 Channel Islands Census (images, every name index)
1901 England Census (images, partial every name index)
