I'm in the camp of, Do it right -- get a lawyer.
Years ago we did some sort of internet fill-in-the-blank type of will ... then we did "real wills" through our credit union. Cost about $250 total; honestly, I thought it'd be twice that -- of course, we're also easy: married only once to each other, no children outside the marriage, no children with special needs -- that was for 1) a will; 2) a power of attorney; and 3) a living will for both of us -- so six documents total -- and it was SO MUCH BETTER than the internet thing we did earlier. The lawyer brought up all sorts of questions that we hadn't considered /options that we hadn't realized could be taken. Best of all, he wrote it up in such a way that it really covers EVERYTHING ... unless one of us dies /the other remarries and brings in new family members to the fold, we need never do anything else EVER. We might want to make changes in the future for grandchildren who don't yet exist, but that would be a choice.
What the credit union route WAS NOT was fast. I saw the sign saying they offer this service, and I made an appointment -- it was weeks ahead. We went in to meet the "get ready guy", who asked us questions we couldn't answer and got us thinking about difficult topics. Then we made a second appointment some two months later, and on that day we saw the lawyer and did the official paperwork. It's one of those cases of, You can have it fast or you can have it cheap. Because we're fairly young and healthy, we were fine with cheap-and-slow ... someone else in a different situation might feel differently.
Different topic: We opted not to go with the put-money-in-a-trust thing. It costs money and reduces the children's inheritance. Instead, we wrote up a lengthy document (not something in the lawyer's possession -- just something in our personal safe for our kids) with our suggestions on how to use the money. In particular, we cautioned them not to make changes /spend rashly in the first months of their inheritance ... and we cautioned them that this is IT; used well, the money could make their lives better forever. We feel comfortable with this because 1) we're both healthy and aren't particularly likely to die before the kids are much older. 2) they are frugal and cautious with money and are likely to take our advice.
