A holographic will is the way I've gone because I don't have a large or complex estate, no kids and few beneficiaries. For others in this situation, it can work out.
I also have a separate Letter of Last Instruction, which indicates the location of the will, the location my financial records, safe deposit box key, the named executor and the reason certain people were left out of the will.
Of course, if you have a much more complex situation, an experienced and competent lawyer is the recommended way to go. This is what I had my parents do, even though they thought they could do it cheaper. They ended up with a Living Trust and are happy their wishes will be carried out, as planned.
