The benefit that I see in these services is the free year of registered agent service and the other side features. I would do it myself if I thought I could find comparable prices on the individual elements if I did it myself.

Its not for a startup, I just need an entity to test some projects out and have some liability protection. If I was doing a startup I'd go with a lawyer no question..

If you aren't doing it to make money, and are just doing it for the liability protection, in court that liability protection would be found to not apply to your non-corporation posing as corporation.

to clarify, it would be to make money. Just a small bootstrapped development house where I can try a lot of ideas and have them either succeed or fail quickly.
