Best place to shop for parts in Canada (used parts) What is the best place to buy bike components that will ship to Canada?  I would prefer a Canadian company or someone who ships within Canada to avoid large shipping costs and inport duty.  

I am especially interested in buying used components.  Right now I am interested in buying: 


Some non-indexed bar end shifters for my road bike
A mountain bike fork with disk breaks and no suspension


Where would be the best place to look for this?  I have tried my local craigslist postings but these items are too specific.  I have also looked in my local bike shop but buying these parts new will cost more than buying an entire new bike.  I like to do most of my own work and being a student I have a fairly small budget.  

Where would you look for these parts?
Have a look at PinkBike's Buy/Sell pages.

This is a site for hard-core bikers, there are always parts of various qualities and conditions up for sale.
