I would suggest using HostMySite.com. Windows plans start at 8.95/month and Unix/Linux plans start at $7.95/month.

www.hostmysite.com
www.smarterlinux.com

The reseller discount is 30% off, and setup fees are reduced for resellers as well. The company has been in business since 1997 and is growing rapidly!

You can contact me if you would like some more info... sbell@hostmysite.com or 877-405-4678. Hope this helped!
