Absolutely I am willing to buy scripts. I have purchased many ExpressionEngine licenses, Add-ons from Ellislab and 3rd party add-ons (mostly from Solspace.) Saying that I would not do such a thing is silly because there are many situations where it makes sense. This is true for client work and for my own business needs outside of development. My personal life is coding for fun and curiosity so I probably wouldn't buy scripts for personal usage.
However, not every business is Ellislab. They put out a product which goes much farther than a PHP script. If you can bring the same sorts of value, then you will likely find customers.
