hosting recommendations?

Does any one here have long term relationships with hosting companies
that have knowledgeable and responsive tech support?

I use one company for all of my clients' sites and I am very happy with
them but I am beginning to feel like it might be unwise to put all my
eggs in one basket, so to speak.

I have looked into numerous companies with mixed results and I figure
that hearing from some of you that have first hand experience might be
helpful.

Any recommendations would be appreciated.

Thanks,

David Rogers
