I recently moved to SpeedyPuppy. Even though this is a small operation, it is located in a good co-lo site (Wilshire in LA) and has good service/price ratio. I particularly liked unlimited MySQL db's, unlimited domains, no contracts, and the h-Sphere control panel, not to mention SSH, multiple FTP logins, among many other features. Service and performance have been very good.

I would also recommend a hosting site I used previously, Site5.Com. I left for reasons unrelated to their features or service, which were excellent.
