Wow I am really surprised nobody said Oxeo.
http://www.oxeo.com these guys are top notch, been using them for over 5 or so years now.
Three things matter to me with hosting in this order.
1. SUPPORT SUPPORT SUPPORT AND MORE SUPPORT
2. Fast reliable and if not 100% up time damn close to it.
3. Fair prices
oxeo gives this all to me and more.
