aqua medic dosing pump replacement drive wheel in canada

[e46er]

I need a replacement drive wheel for my aqua medic do ser http://www.aqua-medic.com/product/sp...0-drive-wheel/

Last time it broke I got it from JL but seems it's not on their website anymore and I'm having a hard time finding it from a Canadian retailer.
Aqua medic USA has it but it's $16 plus $20 shipping plus 16% exchange rate
Anyone know of anywhere in Canada that it won't cost me triple what's its worth by the time I get it?
