They must be pretty rare, I went looking and couldn't find a manual regulator. Didn't look as hard as if I actually needed one, but I did search some. All of mine are power.
I've always had the window clunk issue on the 04, I ground the end of it down to almost nothing and it still hit. It finally broke off, and I think it jammed the regulator somehow, which caused one of the arms to bend. That caused the window to jump out of the track when raising it. Replacing it was fairly straight forward, best tip I found was to use some blue masking tape to tape the glass to the top of the door frame. Made the job a good bit easier.
