Are you sure the higher DSL FTTN speeds aren't available to you? Things constantly change. Check with your phone number at the Bell website.
For Bell Internet 5 Plus (70GB usage), the ongoing price is $48.95/month, or a little less if you are in a Bell Bundle.
Bell unlimited is $10/month more, IF
you have a certain combination of 3 Bell services; otherwise it is $30/month more.
Really, you should consider an Independant ISP. I would recommend Start, or Electronic Box for DSL. Both offer 5M/6M DSL plans with 100GB usage, around the $30 mark. And they include several hours of 'off-the-meter' downloads, or 'unlimited downloads' during those hours that do not count against your usage cap.

Start.ca can probably also provide cable service for you, to get you some faster speeds.
If you're happy with Bell, as Kovy suggested, tell them you're leaving to go with an IISP, and see what they will do. Just be aware of their REAL monthly costs.
