I use four different hosts. The biggest problem I've had was an annoying sign-up process (took multiple phone calls for them to take my business!) and misconfigured DNS. No other real problems to speak of. My rule of thumb is to never go for the cheapest, or near-cheapest host. Pay even just a few extra bucks a month, and it makes all the difference. The very best host I use charges about 3-4 times the cheapest going rate for shared hosting, but they've handled everything excellently, including some big traffic spikes, and offer good technical support.
