I used to be with HFB, but couldn't afford it anymore, downgraded to Dayz.st. I looked and saw SS.com was horrible. can't say much about Dayz.st support either tho. Haven't tried Vilayer, but cost more.
I think HFB shut down. SS has TERRABLE customer service, and servers go down right much. They offer 3 months for $54... im a sucker for a deal, lol. I should have went back with VILAYER. Will after 3 months is up.
I use to have 3 or 4 servers with Vilayer when I had a community up. They have problems like everyone else, just not as much. And they have really good customer service for the most part.
Sorry for the long off topic post.
