Do you need ASP specifically? Or do you just need dynamic control? If your pages are not yet developed and you can go another dynamic route, then you have more choices available.

The cheapest/reliable servers I know of don't run NT/2000/backoffice, so they don't advertise ASP (none offer coldfusion either) - you'd have to use PHP and other open alternatives.

If you want to go the open route, www.coastlandtech.com is great, and www.pair.com offers some nice accounts as well for a larger bandwidth requirement.
