HostMonster seems to offer only one type of hosting plan, with which you currently get 1500GB of space and 15000GB of monthly bandwidth.

You can have unlimited domains on one account.
Customer opinions on HostMonster are for the most part favorable, as far as I've been able to find out. I have not been able to uncover any money back guarantee on their sales pages, however.

We've had numerous people perform jobs on the site and everyone has had exceptionally smooth access to the site. I would definitely recommend these guys to others (and have!)"
