I really like ASVhost, mostly because of the super-fast and super-friendly customer service.
I'm used to fighting my way around websites and hosting providers but with ASVhost I haven't had any trouble (at least so far! Crossing my fingers it stays like that!)
I've had some issues, as we all encounter, but they have all been solved in a very timely manner.
I should add that it is priced competitively as well.
