I recently signed up to DO and I've been happy, admittedly my needs are very simple but they were very helpful in getting my site off the ground. Even though its unmanaged, there's plenty of KB articles, and if you get stuck, they were there to help.
ASmallOrange used to be good, I wouldn't recommend them anymore. When I left ASO I tried out two companies, EuroVPS and WebFaction. I'm still with WebFaction.
