Depends on what your looking for... If your looking for a paid hosting service, then definitely RTB or Kaphost, If you can't afford a hosting service, I'd look into CBMHosting (I'm the co - owner) it's fast, reliable, and free hosting 22 clients and haven't had any complaints so far that are serious, all the complaints have been in the past but have been fixed. We've been up and stable for about 5 months now. Some of the servers you see occasionally are being hosted with us :) Pretty funny too, cause some people think that CBMHosting servers are RTB.
