I would suggest avoiding a 800 number unless you can man it 24x7. Answering machines are a customers worst enemy when looking for tech support, therefore they can get pretty pissed when getting the answering machine and their sites down. I have actually helped out hosting companies whom were loosing big $$ because their 888 number wasn't manned 24/7 and customers expected support right away. You'd be shocked at just how much a 800 number does cost when not manned 24/7
