LLCs are relatively new, but there is nothing wrong with them. You have to register and file articles with the Secretary of State, so I don't see how that's different from incorporating.
"The main benefit of an LLC or a corporation is that these structures limit the owners' personal liability for business debts and court judgments against the business.
What sets the corporation apart from all other types of businesses is that a corporation is an independent legal and tax entity, separate from the people who own, control and manage it. Because of this separate status, the owners of a corporation don't use their personal tax returns to pay tax on corporate profits -- the corporation itself pays these taxes. Owners pay personal income tax only on money they draw from the corporation in the form of salaries, bonuses, and the like.
Like corporations, LLCs provide limited personal liability for business debts and claims. But when it comes to taxes, LLCs are more like partnerships: the owners of an LLC pay taxes on their shares of the business income on their personal tax returns.
Corporations and LLCs make sense for business owners who either 1) run a risk of being sued by customers or of piling up a lot of business debts, or 2) have substantial personal assets they want to protect from business creditors."
