I like the service and support at hostway. http://www.hostway.com
If you are on a budget and dont need much support these two have been reliable:
Winsave

Hostsave

One I would suggest you avoid at all costs is Gisol. They were down at least 20% of the time I hosted with them and it took an act of congress to get any support.
