$2500 USD seems to be a common entry price point for crappy .coms as sold by large domain holders like buydomains or whatever. I think that's simply based on the the fact that its sort of a sweet spot price that nearly anyone is willing to pay for a domain for their business. And I don't think .CA should be 10% of that because it is really the same for Canada or the UK or anywhere else. If you're in business, that's just an amount that nearly anyone should be able to afford for their business. Of course, the price should go up from there based on quality & popularity.
So for basically $3K CAD on this one, yeah, I think that was fair.
