So, I personally own some kimsufi's, and I run a hosting structure for CS students with another since 4 years.
The things you have to know about Kimsufi is:
- they are full dedicated servers, fully capable of handling a decent charge
- they are second hand hardware, already made profitable (that's why the price is so low)
- you should change change them every 4 years so that you won't run into hardware issues
- you can do whatever you want with them, there's really no chance to lose a kimsufi thanks to the remote control console which can make a reboot on a minimal image
- you can do whatever you want with them, really. The bandwidth is really free and unlimited, no bullshit.
- the OVH network is really strong. In 5 years of use, I've never seen any downtime of any of my servs.
For me, that's the best choice for non-critical hosting. They are unbelievably much cheaper than everyone around (except online.net, who has a weaker network), with twice as many features, their greatest community manager is the CEO (checkout @olesovh), things just work everyday. When they don't, just check http://travaux.ovh.com . No bullshit about the problems (cc PlanetHoster, DreamHost and the like).
I'll be happy to answer questions if you have.
