> when they were only £7 each
Yes - they're £9.25 now, but you need to buy the important ones (grandparents, gt.grandparents etc) otherwise you can't find out names of parents etc.
It's not applicable in Toolz's case because her father has died, but for anyone interested in researching their family trees, the most important thing is to ask your surviving relatives for as much information as possible now :) :) I never knew my grandparents and only knew one aunt, so had a lot to research :) Even after 20 years I still have a long way to go. Only a month ago, I met a second cousin for the first time (his mother and my mother were cousins). I didn't know he existed until last year. It's so interesting finding out about your family and, often, the hidden secrets and feuds :) :)
I use Ancestry - it's not cheap, but it's well worth the money.
