I could build my own table or service my own engine, but I don't. I prefer to let more experienced people do it, and spend my time doing something else. Once people realize that intellectual work and property are worth something - such as someone creating an action and charging for it - we could finally move into the 21st century in terms of business.
...but I know the feeling - I hate paying for stuff when I think somewhere in my heart that with a little effort and time I might be able to do it myself. That never works out for me though - I just spend a lot of time, and end up unhappy with the end result.
Pay for an action if you find a good one, and believe you'll use it often.
