are you comparing shared hosting services between godaddy n exabyte? i dont think the shared hosting for exabyte is 500 per year.

u dont have to worry about bandwidth. Start with low, then increase when it reaches 60-80%. Take note that using CDN will greatly reduce your bandwidth as well.
there are other things to consider as well such as when using shared hosting, the server resource such as cpu load will be limited as well. my suggestion is, as the site grows, u upgrade ur hosting.

my suggestion on hosting is might be better use hosting from there rather than take one from malaysia. try research other hosting provider as well rather than comparing between those two only.

sum1 in the same boat as me who got fed up with exabytes. after i have read your post there, conclusion is they have a really lousy support.
in your case, if their support had apologize to their users instead of blaming on user, they wont lose their customer.

in my case, i used to have reseller acc with exabyte, and was so angry with their support for my request.

i have nothing against exabytes services, their services are great. just fed up with their support and their attitude handling customers.

yes. but i think sum1 in billing department, not technical.
