Well I got them a Fitness Depot by Chinook centre. I just did a quick search on their website and it seems that there is a new generation recently released and they are about $100 more than what I spent. Mine weren't the Urethane set. Also, I signed up for some Aspire website and saved $20 on my purchase.
Here is the link anyways:

You could check online in the States as well with the loonie doing so well. Although I would hate to see the shipping charge for something like that.
