I am doing some research on different hosting companies, and I need some feedback. I was wondering if anyone has used or done business with hostgator.com. I spoked to a rep this morning, apparently their tech/sales offices are in Houston. Servers are in the Dallas/Plano area.

They offer 3 different plans:

Low: 350gb disk space, 3,000gb bandwidth $8.95/month
Med: 600gb disk space, 6,000gb bandwidth $9.95/month
High: 1,000gb disk space, unlimited bandwidth $14.95/month

Would any of these plans be a good option for 500,000 visitors per month? These prices seem awfully... low...

Or can you recommend a good but inexpensive hosting company?

Thanks in advance for your smart remarks... I appreciate your help.
