Are you asking about 15Mbps?  If so, most of them do.

What are you looking to do with your network, which apps will you be running, future growth, VoIP?  etc ...?  Please add some more details and we might be able to help more.

If you would rather call and speak with a pre-sales support rep, here is a link to find the phone number:
