I have been using OVH to host my main projects They offer dedicated servers for the hobby market, at unbeatable prices (http://kimsufi.fr, you'll have to look for your local OVH distributor), but also top-level servers at very good price. Plus they're very good (have awesome peering/transit quality, unbeatable prices, 3 datacenters and 10 years of experience).

For my own thing, I've got a shared hosting at SurpassHosting.com. I used to rely on Dreamhost to host my blog and do random tests, but they're just crap. Surpass is just good for what I need in those cases...
