Cyberwurx
I used all of the rest. Cyberwurx is just about the only one that treats their VPS clients just like their Dedicated ones.
They answer their tickets in 2 to 5 minutes.
You can bargain with them for a good deal. Just get a sales rep and start asking for more than a package gives. Really easy.
Their shit is up!
Most packages come with 5 class C IP's!
And they are around to work on shit... No, oops, we all were on break for 1 hour... I used to have to deal with that kind of shit, but not anymore.
They also know how to setup a server correctly! My old one was running about 2.4 to 3.8 with tons of spikes in the 10 or 15 range for server load on a Quad core server. Not good! They blamed it on Wordpress. Whatever...
With Cyberwurx the same server, with many more sites on it now, runs at .04 to 1.1 load with spikes at 1.8 to 2.1.
Try them out if you are looking for a no bullshit option.
