Where are good, popular and cheap options to run FreeBSD in a VPS? (From the three should I pick any two?)
There's also ARP Networks (http://www.arpnetworks.com), which seems to have a good reputation, and RootBSD (https://www.rootbsd.net), which seems expensive for what you get. I haven't personally tried either.
I've had both from them and have found support to be excellent. Honestly can't say enough good things about these guys.
FreeBSD 9.1 Amazon ami has been released. I've been running on FreeBSD on EC2 for a while without issue.
(at least on 8.x I had to move kern.timecounter.hardware away from HPET)
