I'd like to either fix it inexpensively or donate it. Or trade it, but I don't think it's really worth anything. A few years ago the Ecology Action Centre was running something called Bike Again! but the webpage looks like it hasn't been updated in years, so I don't know their current status. I e-mailed the EAC - hopefully they'll get back to me early next week.
Update: Yep, they're still going! Their new website is here. I never thought to just search for Bike Again! again.
If money were no object, I'd buy one of these:
The only thing it needs is a light and a basket! It'd be a ridiculously stylish "utili-cruiser".
There's also Halifax Cycle Gallery - I like their philosophy and their website is flashy, but it's not very useful, as there aren't any goods or prices. I don't necessarily need to shop online, but I'd like to see what's on offer and what the price ranges are before I'd visit.
If I could get a bike like the one I had in Japan for the price I got it for (~$100)? That would be cool. Also, I think, unlikely. But I will go window-shopping one of these days and see.
