Best rewards to redeem airmiles on?

I've got a little over 1800 air miles racked up and I would like some ideas on the best types of things to save up for/redeem for with air miles. I know that I could get:

175 AMs for $20 Metro GC = 8.75 AM per $1
220 AMs for $25 Rexall/Banana Republic/GAP GC = 8.8 AM per $1

but I'm looking for other ideas too. Any rewards to recommend? Is it worth it to save up AMs for travel?

I'm in Ontario btw.

Thanks for any input, SCers! :)

We use our Airmiles for Cineplex tickets. Get two regular tickets, regular popcorn and 2 drinks. Ends up equaling about $30 reward for 175 airmiles.
