<P>Great question, it's almost like asking how long a piece of string is.  Running a complete business on a single product line is always very difficult to get to a level of profitability.</P>
<P>That said, if you have a large profit margin and a massive supplier system (like a Walmart type buyer), the decision to go it alone is a very valid one.  From what you mention about the product I am not sure you are trying to sell millions of them.  If that's the case, I would generally look for a company with an existing distribution system to either sell it to or partner with.</P>
