When I'm not quein I'm a CPA in real life. That said there are three major things to look at - asset protection, product liability and taxes. Different states do things differently on the all three (franchise taxes etc.) but the federal taxes all work the same. A single member LLC can be treated as an ignored entity for tax purposes and you would still file a Schedule C. S-Corp would flow through net income and losses to you personally, and C-Corp gets taxed at the Corporate level. Your individual tax scenario would help dictate which tax structure would be best for you. I'll defer to the attorneys as to which would work better for asset protection and product liabillty.
