Try the link below. I think you'll find some good advice in it.
My advice would strongly be to avoid the money changers on the streets, 'No Commis' signs or not, and that advice comes after nearly 30 years of Bali travel.
Another link you might go to is this one, http://www.filosbali.net/ForumRecom.htm#CROOKCHANGERS, where you'll find a list of money changers who have blotted their copy books, followed by a list of proven good money changers. Feel free to print it off and take it with you - or anything else you find on that site.
Happy travels.
