That's really not true at all. Saying all scripts suck unless you write it yourself is like saying all applications suck unless you write them yourself. And yet here you are using a web browser you didn't write on the forums for an IRC client you didn't write that runs on an operating system you didn't write. I'm guessing you don't think they all suck, and even if you do, there's a reason you haven't written your own: because as bad as they might be anything you write yourself would probably be worse. The same is true for most people and scripting. While there are no doubt a lot of duds out there, I'm sure there are some decent scripts that are simply beyond what most people could write for themselves.
Unfortunately I don't know what those scripts are so I can't help the OP, but saying there aren't any good ones is just plain wrong.
