I don't know anything about Canbet's casino, but here is some feedback on their sportsbook.
Positives
---------
1. Reduced vig (-107) for many straight bets.
2. Window of time to confirm bets without fear of a line change (don't underestimate this feature).
3. Free and quick Neteller withdrawals.
4. Good customer support.
5. Good user interface.
6. Willing to post unique lines.
Negatives
---------
1. High vig as the money line climbs. In other words, they use a much steeper curve than most books.
2. Will lower one's limits if they don't like the way you bet.
3. Overnight limits are on the low side.
