Death Indexed here - (Using RC ShrinkLink) - http://www.rootschat.com/links/01nxh/
The above is not one of the best search facilities I've encountered as it's quite precise, years alone are not an option, they want day/month although broad
I've used this extensively and I agree that it's not all that user-friendly.
In particular the absence of wildcards or fuzzy searching means that there's a risk of missing information if names are strangely spelled or misindexed.
You don't need to put in an exact date but you do need to do dates in dd/mm/yyyy format, so I just use 01/01/yyyy to 31/12/yyyy. You can winkle out an exact date by repeatedly narrowing the range of dates to get down to just one date. It's a mystery to me why, if the date is in the system, it can't be returned as part of the results.
There are also cut-offs - you can't view births less than 100 years ago, marriages less than 80 years ago, or deaths less than 50 years ago unless the person who died was aged over 80.
Plus points are that the births index includes both parents' given names, and the deaths index gives the exact date of birth from some time in the early to mid 20th century.
The prices are in New Zealand dollars, so for example a death printout (if available) currently costs a little more than eight similar certificates from Scotland's People.
