Definitely agree with this one. I'm just using their $110 USD offering - as many sites as I like, databases, ssh access... git, can deploy rails apps too if needed.
At somepoint I'll have to get down and learn how to properly secure a box and go with Digital Ocean I suspect - but site5 definitely hits the spot for me in the meantime.
Also, their support is fast and excellent.
And no, I don't get any sort of commission or are employed by them :)
