Seriously? If you've got a car big enough to pick one up, you can get very decent ones starting from 40 euro's here (in this size; smaller ones are much more expensive). People move and can't fit them in their cars...
Totally. Most Americans know someone with a pickup truck.

And you can rent a truck pretty cheaply for a couple of hours. The last time I shopped for a fridge it was new, stainless steel, and freezer on bottom (almost all fridges are fridge/freezer combos) and mine was too crazily priced at about $900, delivered and installed. I did some research into quality factors when choosing, though and the SS and freezer config are ones that cost more, so I guess I don't really have my finger on the pulse of used ridge prices, but I know when we bought used SS stove and dishwasher last year they were $275 and $125, respectively. I assume a fridge would be about the same or more than the stove.
Heh. The only thing you won't be able to get nearly for free here is a decent washing machine for your laundry.
Everything else you can get for free or nearly for free, except it'll look horribly dated (but you can paint that!), like
this dishwasher or
this dishwasher. When my mom and stepdad split some 5 years ago, my mom picked up an identical dishwasher to the last one shown, which was also identical to the one they had, up for I think 25 euro. Still works.
Of course, you're going to have to uninstall, load, transport and unload it yourself for that price.
