i think cool edit supports most DX plugins doesn'tit? just do a searc for DX plugin on yahoo. Better yet, i'm pretty sure cakewalk sells independant DX plug ins. The autotune plug in that works well in Cool Edit is Antares. I think there is a new version coming out or it just came out. Its not cheap though and takes some practice to get good at using it manually. There is an auto feature but it is kindof lame for specific purposes.
