I'd also suggest CdBaby.com. Places like iTunes require an agregator (sp?) and cdbaby has pretty good rates and an option if you only want digital distribution. They will also sell physical CDs for you if you want. Could also check out mysongstore.com, they're a pretty good site but you need to pretty much sell directly to people, not through iTunes or a similar system. There was some other Fair Trade Music or something like that which seemed pretty good but I can't remember their name right now. CDBaby gets your music into a lot of online resalers so they might be your best bet. I haven't figured out how the Orchard works but I think they only deal with labels.
