If all of the full name TLD combinations are taken, then I think juangone.com is as good as you are going to get. It's simple, and it even has some assonance going for it. The only other one that I have thought of is juangonzalez19.com, but I still like juangone.com better. Where are you going to register it? I know that Go Daddy sometimes runs sales where you can get the .info and .org domains in addition to the .com for only like $3/year extra.
