I need a large bandwith webhost with ASP and database support (Access or something). Im making a database with over 50.000 potential users.

I found two host co. bellow. Witch to choose?

http://www.tera-byte.com/hosting-web.html
or
http://www.chicagowebs.com/hosting/index.htm

Site at Chicagowebs states that the ODBC Connectivities are limited to 10-20 DNS. What does that mean? As far i understond you need only one DNS form one database, or?!

I dont know anything about chicagowebs, so I would say terabyte, they are preety good...
