We were with a particular hosting company for a while and have always recommended them to our customers as well. Recently, though, their customer service has been lacking in efficiency. I was wondering if anyone has a good hosting recommendation for me. My main criteria is that their support staff knows what they're talking about. I have come in contact with too many hosting companies that are not able to help me troubleshoot issues.

I've been looking at hostgator, hostmonster, and bluehost, but would be open to any other suggestions.
