I will admit, at first I was extremely skeptical of VMBox.co since they originally offered services on HackForums. Someone has told me that they ended providing services after a dumb dispute on that forum where a bunch of skiddies thought that they could abuse the CPU 100% to mine bitcoins and launch DDoS attacks.
I took up their $20/yr 1GB OpenVZ offer in Los Angeles earlier last year to test the waters after that incident, and I've been very impressed.
There is a decent yet consistent network speed and great uptime. I've only ever had my VPS shut down once for routine maintenance, which I don't mind. I've been able to run Etherpad-Lite very well given the circumstances. I/O is a bit on the low side but it isn't really a big deal for 90% of people.
Support has been great for me. Steven and the rest of the support staff are generally prompt (generally 1-6 hours response), and they do have a bit of a no-bullshit policy that I really like. They're quick and to the point. They are however friendly though, don't get me wrong.
