Or you can just learn to create your own custom brushes. They are a valid tool and can speed up your work so I don't see what the issue is? I remember hearing similar conversations over different programming languages, using plugins and many other subjects. The key is that when you understand the principals -or how to do stuff the hard way- you can effectively use so called cheats to improve your workflow. Cheats should be tools to get a job done, not props to hide a lack of ability.
I don't work on textures professionally but I love 'em. I've created a few PS brushes these last couple of weeks and expect to use them whenever I can.
