I signed up to a Hostslayer.com VPS after my US reseller provider went badly downhill with major security attacks and then sold up. After a short stint with my previous host I realized I needed more inclusive support.
A lot of time was spent answering multiple presales questions patiently that would have driven me mad.
The support people are fantastic and usually answer in under 10min any time of day. They've always been prepared to investigate further when they don't have an immediate answer. Recommended.
