Kimsufi are a great low-cost provider, I ran an Atom dedi with a 1TB disk with them for 2 years at around £12 a month. Never had any problems - great bandwidth to move data around, mostly used the big disk for offsite backups. However, an important consideration - they don't adjust their pricing for existing customers or allow the hardware to be upgraded. Around the 2-year mark, they dropped the price for the same server to just £3 a month and doubled the RAM. I was told if I wanted it, I'd have to give up my current server and move everything to a brand-new one. They wouldn't drop the price, and when I asked about doubling the RAM, was told it wasn't an option. They then put the price of my dedi up not a month later. I cancelled the server and have run my own hardware since then.

Good for a specific use, but as the low price implies, there is no option to scale in future.
