bernie, we made our wills some years ago, with the help of a local solicitors. I don't think they were very expensive, but whatever it was (and even if it had been expensive), it's really worth the expense. And about 6 months, we dug them out and realised that they were in need of revision and updating. Which we did with the help of a friend whose business it now is to help people make wills. (he used to be an actuary). We are so pleased that we've got our wills up to date - there is always the worry that, if you don't make a will, then all or most of your money will go to the government - and none to the people in your life who matter!
Just look around and find someone who can help you do it for not so much money - you won't regret it!
