Yeap us! @austinpawers xFhost.net hosts over 125 xenForo communities, we have also just expanded into a second data center. We co-locate all our servers in both facilities. I would be happy to answer any questions you might have.I believe someone here has their own hosting going, with dedicated servers.
Your plans do look good. If I wasn't with a good VPS now, with cPanel I would probably move
I am with WiredTree, which I am happy using them for almost two years now. Knownhost is also another well-reviewed company. Both companies have great support team. I learn about these web hosting companies from webhostingtalk.com as mentioned above
Sorry @Ken Black, just noticed you specifically stated VPS... and no, they are NOT the best... There are MANY more that are better. If you do not need a managed VPS, then I would whole-heartedly recommend RamNode, specifically the KVM solutions they have. They were my first VPS and their support (when I needed it) was great. Price (up to the 2GB plan) was competitive and they are RAID 10 SSD. I still have one VPS with them (serves my blogs till the account needs to be paid again - at which time I will place them on my own server that I have configured to set up VPS's on).
