Hopefully, one of those will work for you. I imagine kuertee's mod in particular could be good, because they often are, in my experience. Good luck, whatever you decide!
edit: Oh, and be sure you have disabled all auto-saves in Oblivion.ini - there are quite a few enabled, by default.
(edit: Nono, not TEXNexus! Sounds like a recipe site, or worse...)
