Don't know if this is useful information or not, but I will submit it anyway...
One of my colleagues at Aiken High School opened an account with simplehost.com for one of his projects. As a favor to me he installed Moodle via Fantastico so that I could try it out.
I imported a small course into this Moodle and have played with it for a day or two now. Everything seems fine.
Simplehost.com claims to offer Unlimited Disk Space & Unlimited Email Accounts and more. I have no idea how they can afford to do this. Maybe it is a scam. I certainly do not know. This does seem like a reputable company, though.
Anyway, if anyone else has any experience with this company, maybe he or she will post some more info here. It might be helpful to someone who cannot afford to use a Moodle Partner.
