What you should do is go to nullsoft and checkout a bunch of the ones offered there for yourself. I don't have any personal experience to recommend one for you, but I have found plugins to be such a personal preference thing, that I just download and try them for myself then delete the ones that suck. Most of them should stay activated when you select them in winamp, then load winamp w/ RR. The only one I have used is DFX 7 and I can tell you, it stays active. I didn't do very much with it, but it looked nice.
