practicality

For my Canadian friends - how easy is it to find a cheap tv out there? Doesn't have to be huge or a flat-screen or anything, although it does have to have A/V jacks and not be like...10". The cheapest I can find poking around online is $80 new for a small CRT, but I have no idea what used prices or like or even where one would find a used tv. I've got a 14" CRT here I could concievably bring, but it's really bulky and will require me bringing another box just for it, pretty much. But at the same time, I'm not sure if I'm going to have a hundred bucks to drop on a tv (thanks, Air Canada ><).
