Rogers High-Speed Extreme 
Roger's junk email today has an offer for
Extreme High Speed. The claims:
- double upload speed, to 800bps
- double download speed, to 5Mb
- no increase in cost
- one-time purchase of a Extreme cable modem at $99.95 (plus a $20 rebate)
Might be worth investigating. Of course, this is a Limited Time Offer, expiring June 30th.
