I signed up for a Exigent VPS several weeks back and have been using it on and off. I loaded mine up with a configuration that would allow vhost mail hosting and webhosting. It ran fine, the bandwidth to the VPS itself seemed fine.
To be honest I have been very happy with the VPS service, so much so I recommended it to others. Since we signed up during an introduction of new hardware/services, we actually got a good sign up cost.
I don’t use mine currently, as I moved my services back to shared web hosting, but tempted to hang onto it for a bit longer as its good to have. Besides, if I get rid of it, I wont get another for the price I am paying at the moment.
