Honestly I say when your in your building phases of the site, its not a bad way to go as you just need a place for it to setup your account. While your working on the site, if you feel like you won't have issues then stay, if you are (ie: slow server) then make the switch. As most companies are now using cPanel and such, its easy to backup work and change nameservers for the switch.

Try ixwebhosting. They offer that for $5 per month.

As the OP requested I'm goingto post a hosting a few plans where unlimited disk space and bandwidth is offered:
Webhostgiant.com - Deluxe plan - $9.59 (multiple domain hosting).

Has anyone tried them? I wonder if they allow audio and video downloads on their hosting?

Check out Yahoo hosting

Hostgator has a plan with unlimited bandwidth. The next lowest plan (below unlimited) is 6000gb of bandwidth. So unlimited has to allow higher than that. It's not unlimited disk space but it's 1000gb of disk space for the unlimited bandwidth plan.

It's not true unlimited, of course, but it is "for all intents and purposes" since so very very few of their customers will actually need beyond what they had in mind. If you read the companies' various responses on this issue you'll see that it's mostly because other factors are almost always the limiting factors. Example: How do you use over 6000gb of transfer, yet not max out the CPU? Not impossible but hard. They say that bandwidth is so cheap nowadays it is "essentially" free to them, it's just the server resources that always cause the bottlenecks. CPU, ram, and to a lesser extent disk space.

It's more like they have lots of extra bandwidth already, and each heavy user is counterbalanced by the hundreds of customers with really small sites and usage.

well, unlimited plans are usually limited in a number of uploaded/stored files
Hosting policy should be examined first

What have you heard about IXHosting? What kind of problems? I ran across their site the other day and simply could not believe their offerings. . . what have you heard?

Google it as "IXwebhosting user reviews", and you'll see A LOT of complaints about them. Yes, a lot.

Actually, I don't go with the bandwidth stuffs. I go with the CPU Usage. Bandwidth is not that important to me in shared hostings. That is based on my opinion.

Yes, there are lot of hosting with unlimited bandwidth and unlimited space, and some of them are cheap, too
