I've had a server from Counter-Strike.com for 2 years now. I've finally had to close my doors, due to personal reasons, but however I plan to return as a customer once I have the opportunity.
If you are looking for quality CS:S 100tick servers, you've found the right place. I've had a server in CHI and NYC, both have been fantastic. You will not be disappointed by your order for a server here.
Support is absolutely amazing. I have never had to twiddle my thumbs while waiting or try and fix something I couldn't possibly fix from my end with this support team.
My only one complaint (because no one can possibly not have at least one right? ;p) is that I didn't get a 1000fps server.

(Unfortunately they closed out my account before I could get to my CP support reply, so I don't know what they said.
..PM with reply to "justnat3"'s last support ticket please??)
