Ask HN: Best service for finding a virtual personal assistant

I recognize this question has been asked before on HN. But I haven't seen a post in a while, so I thought I'd ask again. Can you share your views on which platforms are the best for finding virtual or remote personal assistants. I'm looking for a part-time assistant to assist me with regular tasks, not a one-off type service like Fancy Hands. Ive tried Get Friday in the past, and wasn't thrilled. Open to suggestions. Also curious if people have a preference for oDesk or eLance for these types of requests. Thanks
