vBulletin hosting accounts?

I need to grab vBulletin hosting account.
50 gbs of disk space, Linux. USA
After searching in google I discovered: HostingSource.com web hosting accounts.
They seem to be good by I wonder if they are the only providers? Should I stop or continue the search?

I love the speed of the site, the uptime, the support when needed (few and far between), and the features (the automatic backups are wonderful especially).
