I am not a big fan of the LLC. The primary reason is that all income is by default self-employment income and as such is subject to self-employment taxes. However, this is not really much of an issue unless you have taxable income from it over $50K. If you wish to discuss it further, pm me. Otherwise it is a bit much for a forum.
Secondly, if you are a single member LLC, most times you are filing a Schedule C as a disregarded entity on your 1040 and face the same increased scrutiny as a sole proprietorship. And an examination of the LLC can quickly become an audit of your whole return. This is much less likely if you operate as a corporation.
