I've been using CatalystHost for a few months now since I won the managed VPS offer from them in Feb.
I have only contacted them a couple times to help me install things on the VPS as I try to do things myself first or if I'm really busy ask them to do it for me and they have gotten it done very quickly. They treat me like a paying customer and I am very grateful for that.
Now the best part that makes me really think they are one of the best VPS providers around here is due to the control panel issue. When they switched panels back to SolusVM there was a discrepancy in the resource information in the panel. Knowing they were busy I sent a low priority ticket about it notifying them that they gave me some extra BW and Disk Space due to the error. @Jarland told me that I could keep it and to think of it as gift.
That was extremely nice, as it gave me 10GB extra space and 4 times my BW allotment. I then proceeded to ask if they could fix the fact it told me I had the wrong amount of Ram and Vswap because my OCD about that bothered me. Mind you, I am not a paying customer and originally had 256mb of ram.
@RyanArp then told me he fixed it, and to my surprise bumped me up to the 2GB of ram to match the panel.
This is beyond my expectations of any host, and I just expected them to make it reflect my 256mb of ram, but what they did was absolutely phenomenal.
Thank you again CatalystHost and all that you do.
