(See also postings on main Lancashire board about 1841 census CDs)
S & N do Lancashire CD's priced around £50 per set (see
www.genealogysupplies.com). They don't have name indexes but do have area and street indexes. Some years have name index CD's sold separately, but not sure if they are complete. The images of the ones I've seen appear to be quite good.
I think Stepping Stones (
www.stepping-stones.co.uk) do a cheaper 1841 set, but not sure about the overall quality of the images.
If you are interested in Manchester or surrounding area, note that some of the 1851 enumerators books were badly damaged and many entries don't appear on the CD's
You could also try
www.ebay.co.uk. There are often full sets, indexes, and single CD's from sets up for auction. (If you are researching a small area you may not need a full set.)
The Manchester and Lancashire Family History Society (www mlfhs.org.uk), do name indexes to some areas and also transcriptions of some of the unfilmed 1851 sections.
Hope this helps.
