where to buy old parts in canada?

I've been looking through tons of online canadian stores as well as actual retail stores. i've looked and looked and cant seem to find an Asus A7V133 for a reasonable price anywhere! two places had A7V133-C but they were VERY unreasonably priced $150+! even the A7V333 is only 160! does anyone know where i can pick one up for $50(Canadian) or lower?

Are we talking US or canadian funds here? There is a sticky on Canadian online venders up top..if it is not there then your only chance is ebay.

Sorry.
